Canon 5DSR Review for Landscape Photography

In Reviews On Thursday, July 2, 2015

This is an in depth review of the Canon 5DSR for landscape photography with a focus on image quality. I’ve decided to write the review as a series of questions that people might have so that I can really get into the nitty gritty of what the camera can do. There are several comparisons with the Canon 6D. The image quality of the 6D is as good as or *slightly* better than the 5DmkIII, so the comparisons are directly analogous.

Just how much better is the resolution of the 5DSR compared to the 5DmkIII or 6D? Is the resolution too much for Canon’s lenses?

Going from 20mp to 50mp is a significant jump and the difference in resolving power is vast. There is quite simply no contest between any of Canon’s full frame cameras and the 5DS when it comes to resolution. For making big prints this is a revelation, but if like me you just like capturing the most richly detailed images possible, Canon is now the class leader. Here are 3 examples shot with the 16-35 f4L IS, 50mm 1.8 STM and 70-200 f4L IS. Hopefully this answers the question as to whether the lenses are now the limiting factor….they aren’t.

The resolving power of the 5DSR is incredible. With sharpening the results are even more impressive.

The relatively cheap 50mm STM makes the most of the 5DSR's resolution advantage.

This example shows a similar gulf in resolving power. The 5DSR is incredibly impressive in this regard.

A similar shot with a 70-200 f4L IS at 200mm shows that with good optics the 5DSR is in a class of its own

What if we downsize the 5DSR files? Is there still an advantage?

This question popped up when I posted this review to a forum. I’d have to say that I don’t agree with the idea of crippling the 5DSR by downsizing. If you are going to downsize then why buy the camera? Nevertheless what this does show is the kind of difference you might expect in smaller print sizes in the 18-24″ range. The difference is still clear to see. I should point out that I sharpened both crops to what I consider optimal, since the sharpening was different it could be argued that the comparison is still unfair, but I did my best!

When the 5DSR is downsized and sharpened it produces near perfect results. However the gap is now reduced.

What is the diffraction limited aperture on the 5DSR?

I’ve done a few aperture tests to determine which is the ‘sharpest’ aperture and whether a smaller aperture is justifiable for increased depth of field. Obviously the conclusion is subjective, but my thoughts are as follows:

  • f/8 no visible diffraction – this will be the aperture I choose when I don’t need a big depth of field.
  • f/9.5 looks ever so slightly softer – the difference is almost impossible to spot, no practical difference
  • f/11 ever so slightly softer still, little practical difference – this will be the aperture I choose when a large depth of field is required
  • f/13 visibly softer than f11, easy to tell apart from f8
  • f/16 soft at 100% – I would only use this aperture if I had to for a long shutter speed
The 5DSR performs best at f8 but it is only at f11 that any loss in sharpness due to diffraction becomes noticeable.

Does the extra pixel density of the 5DSR act as a focal length multiplier?

One of the dilemmas I have when backpacking is which lenses to bring. I like to cut weight where I can and lenses are heavy! My current choice is the Canon 16-35 f4L IS the 70-200 f4L IS and the new 50mm 1.8 STM. Occasionally I’d wished that I had a longer focal length or a 24-70 to plug the gap between my two zoom lenses.

The 5DSR allows heavy cropping and you can use a tight crop to effectively extend the focal length. So a 20 megapixel crop from a shot at 200mm should give an image very similar to a 6D/5DmkIII image shot at 320mm (roughly). Below is a comparison showing this concept. As you can see, if you only need a 20mp output, the added pixel density of the 5DSR gives you greater reach.


If anything the 5DSR has fractionally more detail in this image despite a much wider field of view.

Am I now limited to f/8? Isnt that going to affect depth of field? What if I have a close foreground?

The extra resolution is ALWAYS a good thing. Having 50mp as opposed to 20mp can only make your images more detailed, not less. Importantly, you can shoot at the same apertures as you were previously and still get a massive resolution benefit, it just won’t be the absolute maximum possible. One thing I wouldn’t do is shoot at f/16 or smaller, you really are butchering the camera’s capability to resolve.

Below is a comparison of the 5DSR with 50mm at f13 and the 6D with 50mm at f8. You can see that the 5DSR is still far superior.

At f13 the 5DSR still achieves great resolution much better than the 6D or 5DmkIII

Has the Dynamic Range improved and does it matter?

Canon has come under a lot of flak since the Nikon D800 appeared for failing to keep up with the Sony sensors, particularly regarding dynamic range. People then make outlandish statements that ‘Canon sensors are terrible’ and then an internet argument ensues. It’s important to remember that whilst Dynamic Range is great, it’s not the be all and end all. For a landscape photographer the difference on a pixel level at low ISOs between the Sony sensors and Canon sensors is invisible without big pushes of shadows and highlights. In general that means a high contrast scene shot into the light. For example sunset images that include the sun would greatly benefit from increased dynamic range to avoid the necessity of bracketing. I shoot these scenes a lot, perhaps to a fault, and I can honestly say that I have never thought “I wish I had more dynamic range”. Besides, whenever I have been on a shoot with a D800/D810 owner they have always bracketed those scenes anyway, just to be sure!

Canon doesn’t seem to have made any real world improvement over the previous generation.

This is an extreme edit from a single exposure. The foreground is pushed 3.6 stops to get the finished image.

This is an extreme edit from a single exposure. The shadow areas are pushed 3.7 stops and a lot of contrast was added (exaggerating noise). A small amount of noise reduction is applied.

What about image noise at low and high ISO?

It’s pretty difficult to make a realistic assessment on image noise without complex analysis, but subjectively it appears like the 5DS produces slightly more noise ON A PIXEL LEVEL than the 6D. When the 6D is upsized or the 5D downsized you see parity but with the 5DS withholding more detail. I’d have to say that I am very happy with the noise performance at ISO3200 and wouldn’t hesitate to use it for astro work.

Overall the 5DS and 5DSR seem to have similar noise performance to the previous generation but there is more detail.

Aren’t vibrations going to make the resolution useless? What about hand holding?

No. In fact you can hand-hold the 5DSR very effectively and still resolve 50mp. The logic for this is actually very simple. The pixels are 1.6x smaller (across) than the previous generation of Canon cameras. If you use a shutter speed that is 1.6x faster than you previous hand-holding limit then you will get the same level of sharpness on the pixel level. If you are shooting on a tripod in the wind then the vibrations need to be 1.6x less. Or looking at it another way you need to use a focal length that is 1.6x wider! So it will get technically more challenging to resolve all those pixels, but most of the time good technique will ensure the best possible image quality.


I had to capture this image handheld because both of my tripods were tied up shooting a timelapse. The settings I used here were quite conservative, I probably could have got away with 1/20th with IS on.

Do you see Moire/aliasing?

I eventually managed to induce moire after photographing my suit at at various distances (I tried all manner of other fabrics without success before a friend suggested trying a suit). There was only one image that absolutely nailed the correct weave pitch to get bad moire but still, its going to be a problem if you shoot fashion. As for achitecture…I tried and I tried and I just could not cause any moire.

Will processing the files kill my computer?

Probably, yes…..My computer was built to deal with large amounts of data as fast as possible. I spent over £1000 on the internal components alone just 4 months ago. I’m running an i7-4790K @ 4.0GHz with 32GB of high speed RAM and 3 Samsung Pro SSDs. My hard drives and scratch disks are set up to help Photoshop and Lightroom (and After Effects) run as smoothly as possible. But at times I find processing the 5DSR files a bit sluggish. This is particularly true when using Lightroom’s new ‘Merge to HDR’ or ‘Merge to Panorama’ functions. Essentially things run at half the speed I am used to with the 6D and 5DIII. At least the Lightroom sliders are still smooth!

My new PC is no slouch, but it's not as snappy as I'd like with 5DS files!

What about ergonomics and usability?

Canon have always been leaders in menus, button placement, ergonomics, speed and usability. The 5DS incorporates all of the best features of the line with a menu that is heavily customisable and easy to use. Having used the 6D for 2 years there was next to no learning curve with this camera. I love the fact that it has 3 custom modes on the dial (C1,C2,C3) I use these modes heavily and to my knowledge no other maker implements customisation this well.

The 5DS is brilliantly thought out, responsive and generally a joy to use. It’s all to easy to overlook just how important these aspects are, particularly in light of people obsessing over dynamic range, but when it comes to ‘getting the shot’ these are the things that matter.

The Canon 5DSR is brilliantly designed.

Canon have produced an outstanding camera for landscape photography capable of out resolving every other camera on the market. Whilst users will have to accept what I consider to be minor dynamic range short comings vs Sony sensor cameras, the resolution is beyond question. This camera now sets the Digital SLR standard for landscape photography in all but the very highest contrast scenarios. The ergonomics and ease of use of the 5DS are class leading and it is hard for me to think of any practical changes I might make to the camera. This is the camera a lot of Canon users have been waiting for and I can’t wait to get out to the mountains with it.



  1. How much of that resolution gain can be seen in the corners were the lenses might be the limiting factor? All your crops are from the center of the image.

    • Good question Phillip. As you can imagine that’s highly lens dependant. On the 50mm and 70-200 there is a definite resolution advantage throughout, it just slightly diminishes toward the edges. In the case of the 16-35 there is no resolution advantage at all in the extreme corners. I would have to test this further to understand in more depth.

  2. Hi Alex.. good read.. just picked up my camera yesterday, upgrade from a MK III. Looking forward to using it soon. Interesting about the diffraction.. I’d honestly never considered it before… is it specific to different lenses ?

    • It’s aperture related and independent of focal length. That’s why I cringe when I see people proudly list their exif and it reads D800 f/22 and I think “why buy a D800?”

      • Probably because f/22 on a D800 is way sharper than f/11 on a Canon 5D and if you need the depth of field it’s better to have the distance or close objects sharpish and the center ground sharpish than the distance and close objects soft and the centre ground pixel perfect..

        • Sure Tim, I meant in relation to images that don’t have a depth of field issue.

        • I seriously doubt shooting on a D800 at f/22 on a lens of similar optical quality can be at all sharper than f/11 on any camera of the same segment, i.e. dslr.

          • You might have to do that test yourself. Tim is one of the most respected photographers in the UK when it comes to technique and technical understanding. He doesnt make things up.

  3. Sorry to have to say but this Canon camera may be good but it’s not that good. The Nikon D810 is far better because you have the ability to push up the ISO if needed and get incredible detail. Not so with the canon… Also just to rub it in the Pentax 645z blows it out the water. I know what you are going to say, it’s a medium format….all I can say is AND. And I have one.

    • Sweet!

    • Of course the 645z is better larger physical sensor. Now go shoot at iso 100 with the 5ds and your pentax let’s see what is the difference??? However pentax wants alot of cash for a lense. Two pentax the highest flash sync speed is 125 Canon 200. Also canon has way better glass at a cheaper price and comes with is.

  4. Hi Alex
    Thanks for the review. As someone who loves my 5D mark 2, with the only caveat being lusting for larger resolutions.; I am chuffed to see that you and many others are reporting such great things about the 5DSR.

    As someone who produces prints I can’t wait until I can afford one!

    Thanks again

    • Hi Dave, thanks for the comment. I have long said that I would only upgrade for double the resolution and my prayers have been answered! Alex

      • I have been using 2x 5dmk2s in the studio and for landscape photographer for a good while now, with one of the ads shooting over 100k images I’ve been waiting for a decent replacement and the 5DSR looks like it could be it.

  5. Hi Alex, good review and I agree it’s one amazing camera (I’ve been shooting with the S rather than the R though). I’ve also been surprised by the ease of use in terms of handholding.

    The one question I have is around the diffraction test. How do you determine that this is an effect of diffraction and not just the aperture sweet spot of that lens? I was using the 5DS at the weekend to photograph kingfishers. As I was using the 500mm f/4 with an extension tube to reduce the minimum focusing distance I was having to use the camera at f/13 to get the dof required. The results still looked uber detailed though. Not sure if they would have looked even more detailed at f/8 though…. Hence the question.

    Happy shooting and looking forward to your mountain shots with the new camera, Oliver

    • Hi Oliver,

      Lenses always improve as the aperture gets smaller up to the point that diffraction sets in. So yes, at f8 you would capture more detailed images on all lenses.


      • Actually this isn’t true either – there are quite a few lenses that are at their sharpest wide open. It’s rare but not completely out of the ordinary. And if you want sharp corners, quite a few lenses only improve substantially in the corners by the time you get to f/11 or even even smaller in some cases.. I’ve tested the Canon 24-70 v2 (three copies) and the 24mm end is v sharp at f/2.8 and f/4 but the corners at 24mm only sharpen up at f/11. The 16-35 f/4 (again, I tested three copies) showed the highest detail at f/4 – although at low contrast. The contrast/sharpness increases as you stop down but not necessarily the detail. Quite a few surprises appearing with this lens testing I’m doing. Great review by the way – not meaning to be critical!

  6. Hi Alex,

    thanks for this great review!

    Could you please tell me which L-bracket you are using for the 5Ds R? I have the camera on preorder, but haven’t figured out which L-bracket to get. I am using RRS BH-40 with the RRS lever clamp.


    • Hi Martin, I am temporarily using a sunwayfoto L-bracket for the 5DmkIII to tide me over until I can order a 5DmkIII RRS bracket which I understand fits flawlessly. The sunwayfoto bracket fits OK for my needs but could fit closer.

  7. Hi Alex,

    Good review and well worth a read to answer a few queries I had with this camera that I feared may come up – good news is that they don’t appear to! It seems that all ‘L’ series lenses should be just fine with this body, whereas some folk were speculating that certain L lenses wouldn’t be “good enough”. The resolution looks staggering and I’m looking forward to getting my hands on one and making some big prints for the gallery with it. May wait a while to see if price drops a little and also if any “software issues” arise in the early batches!

    Thanks for the review.

  8. Great review with a lot of great insight into the pros and cons of this camera. Would you consider posting the RAW file for the scene that you pushed 3.7 stops? It would be great to play around with the shadow push myself. Thank you for a thoughtful review!

  9. Great write-up! Can’t wait to get the camera myself.

  10. Thanks for the review Alex, you answered the very questions I had

    Looking for more detail in BIG prints and ever so tempted

  12. Hi Alex,

    Thanks for the best real world review of this camera!

    Hi Alex.

    Great review and you’ve covered all the important stuff that matters as far as image quality goes, with lots of real-world samples, which is always nice to make direct comparisons.

    I have been considering moving up to the 5DIII and 16-35 F/4 before my next trip to Iceland in September, Now I want this one, damnit! The 5Dsr is beyond my budget (especially as a hobbyist) for now though.

    What are your thoughts about the new Canon 11-24, Paired with the 5Dsr?

    • I haven’t tried the 11-24 Neil. For me 16mm is wide enough for most images and the weight of the 11-24 would be a problem!
      I think the 5DSR is a very specialist camera and the 5DIII is more of an all-rounder. Enjoy Iceland!

  14. STEPHEN GREEN 7th July 2015

    Hi Alex

    Thanks for a great review. You’ve zeroed in on what I also consider are things that really matter (particularly handholding & the weight saving ‘pseudo tele lens’ factor) without the chaff that usually comes with reviews.

    I’ve yet to invest in a FF system & like you, want to combine mountain-eering/-walking with photography. For me it’s simply a choice between Nikon dynamic range vs. Canon handling & lenses. I think the latter factors win out. So it’s reassuring to know you use Canon as well.

    Re dynamic range: this might be of interest (apart from using flash of course!)

    • Ken Rockwell isnt exactly seen as the font of knowledge!
      One thing I can say is if you are trying to shoot handheld or there is a lot of subject motion, then bracketing is not possible so the sony/nikon sensors are far superior there. For me that’s never an issue.

  15. Thanks for taking the time to publish this review Alex, very useful looking at it from a Landscape Photographers perspective, you’ve answered all the questions i had and were going to test when mine finally arrives. I too have the 50mm STM and am pleased to see your results. One of the biggest attractions of the camera to me is the ability to crop into images which may allow me to carry less gear, thanks for covering that.

  16. Good review Alex. Confirmed that I need to wait for the 5DIIII(?) I do not think this is the camera for a concert and event photographer that shoots a few landscapes now and then. I am regularly shooting north of 6400 with a lot of shadow detail.

  17. STEPHEN GREEN 9th July 2015

    Oh dear! Handheld exposure bracketing for blending is exactly what I’m planning to do! (for on-the-move shots anyway..not perhaps special effort times like dawn on summit tops. I’d use a tripod there).
    I was hoping that the auto align features in software would cope with slight movement between frames (both for manual blending in Pshop & auto blending in LR Enfuse). That’s the theory anyway. I’ve yet to put it into practice..

    I really don’t like the handling of the Nikon D810. The most important Canon lens I’ll want to use (16-35 f4) appears to be better optically & in build than the Nikon equivalent.

  18. Back in the film days I shot iso 50,64 and 100 slide films – they provided a dynamic range of about 4,5-5 stops – I still have slides from back then that are absolutely stunning. The canon provides 12.5 and the Nikon 14 stops of dynamic range – with both systems – provided you know just a little bit about light and light metering you are able to make wonders in camera and with the addition of camera raw there is no way of stopping you from producing images of the highest quality. So the debate about dynamic range and the canons devastating short comings in this area (- in my point of view -) is only applicable if you are a really lousy photographer that do not know your craft.
    The high ISO does not concern me – I use my 5dsr at ISO 100 95% of the time for the work I need the 5dsr for. I still have my 5d3 as a backup and I love the fact that canon have stayed true to their functionality since there first EOS cameras came out in 1987 – its logical and the ergonomics are great.
    Other reviewers rants about the video – the non tilting screen – the non touch screen – bla. bla. etc – I see the 5dsr as a stills camera to be used with best of Canons optics, and as such I have not been disappointed.
    Someone asked about corner sharpness – with the Sigma 50 mm art and the Canon TS-E 24 3,5 L II, in neutral position – the good glass on these lenses are able to put sharpness all the way into the edge of the frame?

    Thank your for the good in depth review

  19. Hi Alex, First off great and interesting review. I am a professional animal and landscape photographer and I have a question; I have a 5Ds and 5DsR and have been doing various tests on both cameras and then looking at the RAW files at 100% and on both cameras the image appears to be slightly soft and even after using sharpening in post it is still evident is this something you are see in your files at this stage. When viewed full frame they look OK but it’s giving me some doubts about the cameras. I have previously shot with the 5D3 and 1DS3 and the files at 1005 look sharper, I know that is not comparing like for like but would be interested in your thoughts. I also have a Phase One IQ180 and maybe I have got to used to that!! My thought at the moment is to test the focus etc on the cameras and lenses I own but I am wondering if what I am seeing is a characteristic of the files???

  20. Thanks for a great real life review Alex. Really appreciate the side by side comparison with the 60D, looking to switch from the 7D to full frame now I have a couple of ‘L’ zooms and think it’s going to be the 5DSR for me having seen your review.

  21. Hi Alex

    Thanks for doing a great practical review and not one full of bamboozling graphs and scientific mumbo jumbo.
    As I do wildlife as well as landscape I think the 5DS might be better for me as I expect moire/aliasing could be a problem sometimes.
    Really think the crop factor should be a great help.
    Not made my mind up yet on 5DSR or 5DS and plenty of time as it will be a while before I can afford the upgrade..!

    To pick up on a couple of points. What Tim says about sharpness in corners is true but I always wonder why so many lens reviews dwell on this. If you are using a wide aperture it is usually to achieve a sharp subject, such as wildlife or human portrait, with smooth bokeh in the background, in which case sharp corners are not necessary.
    For landscapes you are usually stopping down for depth of field so the corners will be sharp anyway.

    I agree with Alex re blending – always better on a tripod.

    For L bracket I recommend the Arca Swiss – it is strong, sturdy and not camera specific so you should not need to replace it when you upgrade to a new 5DRS 🙂

  22. Excellent article as usual Alex!

  23. Thanks, best review on 5dsr !!

  24. James Guppy 28th October 2015

    Hi when you say “sharpening”, what are you using to achieve this? If you have any tips for software etc. then I’d really appreciate them – I’m currently taking RAW images on my 5DSR and then converting them into DDG files using some pretty basic free thing I got off the Adobe website (the files were too big to import into Lightroom).

    Despite being pretty competent with software/computers, this element of my photography is well behind the rest…so any websites, tutorials, books etc would be oh so gratefully appreciated – I just want to get the best out of my gear!

  25. I just buy my Canon eos 5dsr , and i had for one year also the 6d . I agree with the results of the review.. I think 5dsr worth the money for more details , colors, wider field of view. I just try to get used with the new and more settings that 5dsR have. I want to ask what are the best settings i can do to improve to the highest performance for my camera, compare to the default settins fromfactory. I have an 17-40 ,4, L and samyang 14mm 2.8 , i almost shot landscapes.. Thanks

  26. Simon King 9th January 2016

    thanks for the review Alex!

    just saving up my pennies…

    I’d be interested to hear how you sharpen optimally for print sizes, what you have found works best… 🙂

  27. Simon King 9th January 2016


    meant to ask whether you can see any difference (detail, sense of acuity, contrast, colour , overall impression on viewer etc) compared to 5D3 etc on PRINTS A2 and under? i.e. outside of 30×40 prints, just on normal A4, A3, A2 etc?

    let us know if you get the chance to do a comparison (though why you’d bother is another matter


  28. Jeff Allen 27th January 2016

    Hi Alex
    Very comprehensive review. Like you I have the Canon 6D a camera that Ive been very happy with and still am. I also purchased the 5DS in September last year and have found the same experiance as you and frankly the resolution this camera provides is outstanding, I did however go with the 5DS having a bad experiance of moire even on the 6D with a strongly defined picket fence in the US. Technique I feel is critical in terms of setting up correctly to maximise limiting vibration and the technical solutions provided by Canon help immensly in this.
    Professionally I run one of the largest cinematography camera rental companies in Europe and as such have access to testing tools including CIPA resolution charts and your points are valid nothing else as far as DSLRs go touches it.

    • Hi Jeff,
      I’ve since also purchased the A7RmkII and my business partner uses a D810. I couldn’t honestly say that neither of those cameras ‘touches’ the 5DS but personally I’m just glad to see that there is parity in most ways!

  29. Thanks for the great review and the detailed image comparisons. I’ve been using the 6D since it came out and I liked it in general. But the MP was just lacking for a FF sensor. I simply don’t like to upscale when printing at, say 20×30 and above. I was very excited at the potential of 50 MP and your image comparison made me even more so, then… I found out 5DS/Rs don’t come with WIFI and GPS? Why?! Canon Why?!

  30. Cracking review. Confirmed much of what I understood. Alas for commercial reasons I had to grab a 5D3 quickly after mine went swimming but I will be having a clear out to raise some funds. The PC issue is just the way of the world alas. I run an i7 4GHz but I’ll need to beef up all my storage which adds to the outlay.

  31. I have to say I utterly disagree with you. I’ve used all of the 5D series of cameras and have had success in handholding right down to 1/2 second with the 5D2.
    However I have yet to get a sharp shot from my 5DSr when handholding, after 5 months it’s proved impossible.

  32. Hi Alex,
    I currently use a 5d3 with 16-35f4, 24-70f4is and 70-200f4 is lenses. I would like to upgrade my camera (primarily to get more resolution and dynamic range) before my next overseas holiday (6 weeks away) and am having some difficulty deciding between the 5d4 and the 5ds/r.

    I think 50mp may be too much for me, and the resolution advantage is only good for printing huge (which I don’t do) or perhaps viewing photos on 4k monitors/TV. Although I think it would be nice to pixel peep one’s images and be amazed by the additional detail.

    The 5d4 has much more dynamic range and a slight bump in resolution to 30MP (16.7% at 100% viewing size) and better noise performance. I would have much preferred 36-40MP. I guess I could take panoramic shots for static scenes that require more detail…

    In store, I took some RAW photos on my memory card using 5d3 and 5d4 and resized the RAWs down to 1920×1280, 2560×1707, 3840×2560, and 5760×3840 (5d3 size). I could only see a resolution improvement from 3840×2560 upwards so unless I use a 4k monitor I will not notice the resolution benefit at “final” JPG sizes.

    Also, do you use a 4k monitor and have you noticed the difference in resolution when viewing images at 3840×2560 (compared to the mk3)?

  33. Hi Alex
    I owned canon 5dsr and lens 16-35 f4 is
    the question
    what the best sharper at f ??

  34. Craig Stoklosar 1st November 2016

    Great review! This really influenced my decision to buy the 5 DSR. No regrets. It is a challenging camera to master…but worth the patience.

  35. Hi Alex,
    thanks a lot for your review. Can you tell wich Live View Silent Mode works best to reduce shutter shake and vibration? There are 2 new Silent Modes to choose from in Live View, any experience with that? I have heard Mode 2 is electronic first and second curtain, but I doubt that. Which one do you use on a tripod?

    Hi Alex

    Firstly, fantastic review! You’ve definitely focused on points other people are concerned about specifically using handheld, the result of noise and the dynamic range.

    I’m looking to upgrade from my 6D and have been tempted by the quality of the 5DSR since its release. Matching the AF capability of the 5D III along with the 50mp resolution for capturing landscapes.

    Some reviews mention problems when shooting wider than f/4. I often shoot f/2.8 and lower for portraits and fashion outside, but stick with f/8 – f/11 with studio work. Would this be solved by using a fast enough shutter speed?

    Just after some advise to say whether its a good idea for an upgrade. I have an A7 II as a second body, which I find amazing as a walkabout camera and use of IBIS. I very rarely shoot anywhere above ISO 1600 but if I do I find the A7 II can handle it.
