Canon EOS 5DSr versus 7D Mark II - Feather Detail Comparison
Canon EOS 5DSr - 50.6 MP Full Frame
Canon EOS 7D Mark II - 20.2 MP APSC (1.6 crop factor)
As it is very grim outside I thought I would compare my newly purchased 5DSr with my 7D Mark II. Although I mainly bought the new camera for landscape work, there has been discussion on various forums as to how they compare for bird photography. Although the 5DSr is full frame it effectively has about the same amount of pixels on the subject as the 7D Mark II.
Glenn Bartley found that the detail from the 2 cameras was similar, Art Morris found on the other hand that the 5DSr was sharper, due to the lack of an anti aliasing filter (the 7D Mark II has one). However his tests were with a bank note.
My test was using a Northern Flicker tail feather (found on the ground in a forest I hasten to add). Canon 500 F4 Mark II with 1.4 Mark III extender (my normal set-up). Mounted on Gitzo tripod. AV 5.6, ISO 1600 (to see how they compare at high ISO), feather 6m from the camera focal plane - a typical ideal distance for me when photographing perched birds. Before starting the test both cameras had been micro adjusted for this combination using a Spyder Lens Cal (at the same distance).
Anyway - be interested in your thoughts, to me they look very similar, both in detail and ISO performance. I took shots with and without mirror lock-up on the 5DSr, but could see no difference.
The AF systems are very similar, but 5DSr has half the frame rate of the 7D Mark II. The full frame 5DSr would avoid you clipping off parts of the bird for close encounters in flight, not that this happens too often, but recall my (almost) best Short Eared Owl shot from last year with the 7D Mark II when this happened as one flew right over my head.
Flickr is a bit restricting in this sort of detail comparison, but to get a closer look, download the original file (down arrow icon at RHS of black frame).
I did a 1DX versus 7D Mark II feather detail comparison last year, but on a real bird that time! Have attached that shot below, where as you would expect the 7D Mark II in good light had a distinct feather detail advantage.
Update 20/2/17. Took the 5DSr on its first trip Sunday to try and photograph a wonderful and very rare Bluethroat in Lincolnshire. Must say I am pretty amazed at the results, whilst my feather test proved inconclusive actual shots taken in the field have such amazing feather detail - I am now convinced it is a serious step up from my loyal 7D Mark II. Example included below the Kingfisher shot.
