I switched to the shutter button for BIF probably at least a couple years ago based on your method. I still use AF-on for static birds using a custom recall. I normally don't use tracking at all but your post intrigues me to consider possibly looking into it with the AE-L button since I wouldn't use it much. arbitrage wrote: Uzay wrote:
I wonder how many A1 users using the AF-on instead of shutter button for focusing and are there any advantages?
I switched from AF_ON to shutter AF back in my A9/A9II days. I see no reason to use AF-ON. I do use my AF-ON and AE-L buttons to modify focus modes (AF-ON engages Tracking for whatever AF mode I'm using as my main mode), AE-L used as a custom recall for perched birds with slower ss, lower iso. So I do some of my shooting holding down the AF-ON just like I used to do for all my shooting with DSLRs.
But my main focus is on my shutter. I switched to this to remove an extra button from engaging focus in order to shoot fast BIF quicker (IMO). Only one button to deal with and I feel Sony has a good enough shutter button to reliably hold it at half press without accidental full press when you don't want to fire.
With Tracking available, and full coverage AF points, the reasoning to do BBF on DSLRs is pretty much gone.
The only reason one could make for using AF-ON and deactivating shutter is to be able to MF when AF is struggling and take the shot without having it refocus. I find that if I use MF to narrow in to a subject in tricky/distracting surroundings that then a Small Flex Spot:Tracking will keep on the subject 95% of the time. You can program a button to do AF-OFF for this rare scenario if needed.
