Anton from what I can see if you hold the back button in on option 1 it will disengage the shutter button focus. If you let up on the back button it will activate again on the shutter button . So as long as i am holding the back button in the shutter button functions like a release only. That was option 1

Option 2 the back button acts as a lock . So what happens is the shutter button does the focusing than if you hit the back button once it locks focus and will not release focus until you hit it a second time . So on option 2 it is a focus lock function.

I'm a option 1 on this

So still no way to take the AF off the shutter button and put it solely on the rear button? That's what I need, neither of the above functions will cut it for my uses. Every other camera can do it, but not the AFD III.

Hi
I think you are spot on. Take a look at CF 18 http://www.mamiya.com/645afd-iii-more-info...-functions.html. With the AFDII with CF 18 this is where you set the focus choice of front, rear from the shutter release. Same with the ZD camera. I cannot understand why they took this CF away? AFDIII is not an option for me either. I will talk to the Mamiya rep & complain next week.

Correct -- and yes it was a stupid rework by Mamiya. (FWIW, both the Mamiya version and Phase versions do this and while I have no Mamiya contacts, I have complained to Phase about it!) I wasn't happy about the MLU swap around either.  Anyway,  closest you can get is to use 19-2 and have selectable AF lock.  Irony is, I now leave the AF lock up front using the shutter button to focus and 19-2 option to lock.  Focus locks and Green dot stays lit with one press until you press it a second time.  In use, this has become second nature and surprisingly I no longer miss the "old" way of thumb-button focus.  Regardless, it *should* have remained an option and certainly should be addressed in a firmware update or the next version body!
