I use a Canon R5 (MK 1) camera. If at 100mm my lens focuses quite quickly. If at 500mm I lose shots due to the fact that I have to manually focus it. Or switch the camera on and off. Or go back to 100mm, focus close by and then re-zoom to 500mm. By this time the bird or animal has gone! It doesn’t matter if shooting a BIF with a blue sky or if shooting bird's in a a tree. My Canon EF 100-400mm (and with 1.4 extender) was much quicker than this lens and I am beginning to think that I made a mistake changing! I usually leave lens on FULL and I have tried putting it on infinity, but I experience the same issue. Please can someone tell me how to fix this. Is this a setting change? Firmware is up-to-date. Many thanks.
