Dennis this is something I really wanted to see so thanks for posting.
How fast/slow was the AF when you had everything hooked up. Your thought about TC performance ?? Lastly is this a straight off nothing done file and how heavy was your crop. Looks pretty good. I ask for people that might be considering for wildlife needs. Yeah thats one big Arse bird
Up front, if I could only have one camera it would be my current 5D Mk IV as it is such a functionally rich, flexible and solid workhorse. I purchased the EOS R to complement it, although the EOS R is an incredibly competent camera in its own right.
Back to the A380 shots above, the settings for EOS R were:
- Manual Exposure Mode: 1/1600 sec, ISO 640, F8.
- Large Zone AF:Horizontal
- Servo AF
- Low Speed Continuous Shooting: Tracking Priority (3fps)
I chose Large Zone AF:Horizontal as it was a big bird in a clear blue sky with no BG distractions.
I tracked the A380 as it approached, passed by and flew away from my location. Straight-and-level flight all the way. It basically filled the whole frame at 560mm.
- Compared to my current 5D Mk IV, the AF didn’t feel quite as confident and towards the end of the series, with the A380 flying away from me, the AF did miss on a couple of frames. My (now sold) 5D Mk III never missed this type of shot.
- There may be a better set up for the EOS R that I have not dialled in, it is early days yet.
- Right now, if I wanted to shoot birds in flight, I would definitely take the 5D Mk IV as my prime camera over the EOS R.
- There is probably a familiarity and usage factor at play as well; I am very familiar with the 5D Mk IV so it kind of “disappears” when I am using it, whereas I am still having to think a little when using the EOS R and this contributes to a feeling of less confidence – a user familiarity issue.
- I suspect that after much usage the EOS R will also “disappear” and allow you to just focus on the shot rather than the camera, allowing a more objective comparison between the two bodies.
Just for comparison, here are similar (Raw SOC) 1200x900 crop shots taken with the 5D Mk III (2017) and EOS R (2018) using the same lens, but Mk I and Mk II Extenders respectively. The 5D Mk III shot was taken under clearer sky conditions whereas the more recent EOS R shot had hazy skies that almost looked a bit smokey.
