Thanks Everyone for helping me set up BBF on my Sony! The key was the p 22 Select AF-On!

That's an interesting choice. I'm going to have to give that a test run.

Mark,

This is quoted from the Friedman book. I have set my RX10 IV to BBF using AEL button:
Back-Button Focus (BBF) is like a religion for some people, especially if
they are coming from a different camera brand. It's a style of shooting that
was very efficient in the early days of SLRs; and although modern AF
algorithms now can do the job faster (and most of the time just as
accurately), if you grew up using it it's frustrating to use a camera that
doesn't have it.
So what is it? Instead of having one button (the shutter release button)
perform the job of initiating focus AND taking the picture, BBF separates
those functions to two different buttons: focusing is performed by one of
the assignable buttons (I recommend the AEL button for sheer physical
convenience), and the shutter release button just takes pictures. In use,
place your subject in the middle of the frame, press the BBF button, wait
for the camera to lock focus, then (optionally) let go of the button.
Recompose and shoot all you want – the camera won't try to focus again
until you press the BBF button again. You can continue to shoot without
the need to refocus before every frame.
Here's how to configure your camera to work this way:(note - the squares are right arrow icons)
 First, tell the camera not to autofocus when you press the shutter
release button: MENU  1  5  AF w/ shutter  Off
 Next, assign AF-On to the AEL button via MENU  2  9 
Custom Key(Shoot.)  2  AEL Button  AF On.
 Turn the Focus Mode dial to "S" (Single-shot), and set the Focus Area
to "Center"
 Shoot with your special configuration

Good luck,
Mark

there is no way to do bbf on the rx100 models but what you can do is focus using the shutter button 1/2 way down and then shift the camera in manual focus (this will hold the auto focus until you manually change it or turn the camera back to AF and refocus with the shutter button. I have manual focus set up on the left side of the wheel and combine it with the dmf (dots feature) which show you what is in focus by using colored dots on the areas in focus.

oops I now see you are talking about the rx10 not the rx100 please disregard... Sorry.

Even if thaz true you would still see all the sub menu options although in certain modes some options would be greyed out.

Front button can be rather comfy ... Olympus and Nikon have front buttons That I’ve set to “AF On”.
