Shooting osprey eating and feeding in nest 100 yards away. Using ef 500 f/4 II. ISO 1600. I have an R7 or an R6 II. Curious what folks with experience with this lens would choose. Which body, Add a 1X converter, crop in body, or crop in post. All shot from good sturdy tripod.
Appreciate that as I have not only some of the same gear but shoot under similar conditions. The 500 f/4 II does really well with the R7 and since you're operating at an EFL of 800 that's a great place to be. The R7's AF is not as accurate as the R6 II and I found that it tends to lose birds like osprey when they are diving against busy or contrasty backgrounds (unlike my R5). You'll have to experiment and see if you like the TC on the R7 (raising your EFL to 1120mm). I didn't find it particularly satisfying considering the impact on AF, sharpness, and FOV.
If you are using the R6, from that distance, I wouldn't hesitate to employ a 1.4x III TC.
