Thanks for your help; I have been looking for this for a long time. I read the manual that came with each camera, I even have David Busch's book on the A850 and the A77 and I couldn't find this information (maybe I am dense), where did you find the information (book or manual and page)?
Glad to help.
I wish I could tell you but I'm not sure it's even in the A77 manual, I just know from many years of using Minolta then Sony cameras.
I do think Sony missed a trick with the implementation on the A77. Pressing the multi function selector initiates focus but only on the centre focus point, why they didn't default to the AF point in use (as in "local focus" mode), I fail to understand. I get over this by choosing Manual Focus and initiating AF using the AF/MF button (As you probably know the AF/MF button temporarily switches to AF when you're in MF mode or to MF when you're in AF mode). Anyway, I find this pretty useful as, with "focus peaking" enabled, when you release the button you see which areas are in good focus.
In addition, I have assigned DMF to the AF-A position on the "focus mode dial" (Shooting Menu Item P3). As soon as the focus locks the camera switches to DMF (direct manual focus) and again "peaking" picks out the areas in focus and you can manually tweak it if desired.
Even if it's far from perfect, this is a brilliant piece of kit. I can't wait to see what they've done with the A99.
