So is the Canon R5 a bird photography body? (1 Viewer)

I imagine the RF lens should perform better than it's EF equivalent but there are few you can compare at the moment. I'm not going to let go of my 500mm f4 any time soon!

I was shocked at the AF performance difference between the EF24-70 and the RF24-70 2.8 lenses. The speed difference and hit rate especially in challenging light is like night and day. We will be rewarded with a flood of large aperture RF telephotos in the coming year.

I certainly wouldn't question your comparisons and would in all probability expect any like for like RF lens to be a bit better but out of interest are your observations based on using both lenses at the same time ,same subject, same light etc or a more subjective kind of thought process? I have had the quickest of tests using the RF100-500 and it was instantly fast to focus but so is my 100-400MK 2 when using the adapter as is my 500mm Mk2 with the 1.4TC Mk3.
In all probability I will get the 100-500 because 20% extra reach is not insignificant but neither is the cost of buying the lens plus RF 1.4 TC.

Same conditions. But the difference was in horrible light. In excellent light, the EF does just great. Thank you Canon for making the RF body backwards compatible. The R5 and R6 AF systems are a tremendous upgrade to anything unless you’re used to a 1Dx Mk3 so nailing shots with the newest mirrorless bodies is so much easier. The hardest target is a running toddler in a dimly lit room. :)
