the reason for AF on shutter button is for a more simplistic experience, high/low angles it's easier with one button, remote triggering of AF, you regain all these features with shutter button AF.
I offer that feature existing on super lenses to show that AF Stop/ AF off, was intended for sports shooters to start with,
BBAF isnt the only solution as suggested. No one is sayting that BBF is the ONLY way to do AF!
Numerous folks (myself included) have stated a variety of reasons to use BBF,
because to resolves problems if AF is kept on the shutter button...Reasons for folks thinking about BBR but who cannot understand why to make the effort to adjust its use, so that they can overcome the same limitations of using a camera without BBF.
My Canon S110 only has focus on shutter button. And for a lot of shooting with it, the AF on shutter button works just perfect. But then along comes one of many reasons why I would love to disable shutter button AF, so I can make certain shots that are effectively made less feasible by always having shutter button AF.
Some folks have suggested some other solutions to try, like AF-OFF. In such cases, we have usually pointed out certain situations that are not solved by that particular suggestion, but where use of BBF does solve the problem.
IOW, there are reasons to USE BOTH kinds of control, what is best for accomplishing your goal! And we are stating the purposes fulfilled by BBF...we are not religious fanatics about it, not telling folks to worship a different god than they pray to now.
