Some more fire photos with the R5 on Monday evening. Definitely keeping the R5 on my long glass when I have several cameras on me, it gives so much more tangible reach than the 1DX Mark II. Seems like a perfect duo, high res on long glass and lower res on the wider glass, which is less likely to be cropped in.
Getting so used to the R5 that it basically disappears in my hands at this point. Honestly taking a lot for granted with this camera, I've barely had to adjust exposures in post-processing with how great the viewfinder is, and I don't even notice the electronic viewfinder anymore, it just *works* and it works so great.
EOS R5, RF 35mm F/1.8 STM, at F/1.8, ISO 100, 1/8000th.
Here are a few shots from my first two outings with the EOS R5 using the 500mm F/4 IS II and the commlite EF to R adapter. First two are of Bonaparte gulls feeding on the Niagara River and the third is a Greater Yellow-legs in a pond in early morning light. So far autofocus is excellent, when it gets the bird and the eye it keeps it very well. I have noticed that it does have a problem that early Sony cameras had, where it has trouble locking onto a bird in flight if there is a complex background behind the bird. The Sony's have gotten a lot better at that since the A7III and I expect this could get better with subsequent firmware updates. So far on this shoot it was as fast as the Sony A7RIV with the 200-600 but a bit sharper with the 500 prime.
Interestingly my first take is that every pumpkin is in focus except the one at the lower left. A second look reveals of course that some of the others aren't tack sharp while others are. Still, I found that one out-of-focus one to be a bit distracting.
