A7R and Back button focus
« on: August 14, 2014, 08:19:42 PM »
Is it possible to use back button focus on an A7R? If so, how do you set this up?
Thanks,
Ron

Take a look at Gary Friedman's book which you can download or, someone who owns one may look it up for you or.  A good number of us have the Friedman book on their particular Sony and recommend it....john

I own the book and have been going through it. I tried the index for this back button but could not find it. Can you give me a page reference?

I am not familiar with 7R but i think if you are in AF-C mode just press the multi selector in the middle and get spot focus like when you were in AF-S mode. I don't have any camera right now but i think there is way to do it. I will reply again about Monday if not anyone else reply

See if this works for you.


Go into the Menu

Menu>Custom (go to screen 6)>Custom Key Settings>AEL Button

When AEL button is highlighted press the button that is in the center of the Control Wheel. You will see a list of commands which can be assigned to this button. Select AF On.

This should enable you to use the AEL button to achieve focus without firing the camera.

NOTE: You do not have to use the AEL button, it just happens that the one I used and you may wish to assign another button. If memory serves the commands available to a button may not be the same for all buttons. I happen to know the AEL button can be assigned this function.

I hope this helps.
