First of all really really enjoying the new R5 Mark II for wildlife / action so far 😃. Pre-capture and AF updates along with faster sensor are fantastic! Thank you.
I use back button focus (AF-ON and * set for meter and AF servo while pressing), works great for wildlife. I have a heavy shutter finger and while holding half way down to enable pre-capture for extended periods of time on my subject I accidentally press all the way down and collect a lot of extra unwanted photos. What would be fantastic is a firmware update to allow an option in customize buttons for AF-ON and * to allow pre-capture enable while pressing (along with Meter and AF). That way I use my thumb to press AF-ON (and get Meter + AF servo + pre-capture enable)...then I just hit the shutter button all the way down like normal to get pre-capture images and continued burst images if I hold the shutter button down. Probably a minor firmware change but it would really help me and save a lot of flash and disk drive space for accidental shots while trying to maintain shutter button at half-press.
