[QUOTE="nickt, post: 695862, member: 4923"] [b]Re: Shuuter doesn't release using back button focus with AF-ON[/b] Af-s with shutter button will focus/recompose regardless of the focus area mode. BUT... if you are using bbf with af-s, that is not the typical bbf setup and it will not work in the way the technique is supposed to work. I'll stop short of saying it is wrong to use af-s with bbf. There may be some reason someone wants to do it that way, but it defeats the purpose of why most people use the technique. The typical bbf setup is using [B]af-c[/B] with [B]release priority [/B](menu A1). The method of use is to hold down the back button for continuous focus. You can keep the back button depressed and track the subject, shooting as needed. Or you can hold the bb down and when you are happy with the focus, [B]release[/B] the bb and recompose and shoot. This technique allows you to be in af-c mode but at any instant, release the button and recompose. It gives you instant access to a simulated af-s mode. If you were to set up bbf with af-s focus priority, recomposing while not holding down the bb will likely not allow shutter release. You could probably continue to hold down the back button while recomposing and that would let you recompose via af-s but that defeats the purpose of the "bbf technique". You would simply be using af-s mode activated by the back button only. You don't get the benefit of full time af-c with instant access to a simulated af-s. That is what most users want to achieve when using the "bbf technique". [/QUOTE]
