On my 5D series, I have C3, C2, C1 programmed to be sticky on my standard settings for BIF, backlit and normal perched birds, and M and Av or Tv for more immediate changes, and use muscle memory to flick through. You should be able to click and expand the images here. I download the more interesting ones to look at.
Ugh. Have to find a better way to reduce for uploading. Compared to my hard copies here those look terrible... hehehe..
Your 5D4 is the masked assassin of BIFs man. I used to love my 7D2 and the 10FPS but the auto-focus on the 5D4, for me, hit so much better.
Muscle memory? At my age senility is more the concern. I'm happy with normal memory.
Thanks for the warm welcome - it's appreciated.
