Quick question on the fly!

Is there a way to set up a custom function on a 5DII to switch from ONE SHOT to AI SERVO with one button? I heard it was possible on the mark III but how about the mark II? I don't have the book with me right now. Thanks!

Don't have the II so can't answer but as you are connected to the intewebs you never need to be without your manual - http://www.usa.canon.c​om …rk_ii#Brochures​AndManuals

I believe most EOS bodies let you use the DoF preview button to do that.

Not one button, but one button (the AF.DRIVE button) and a twirl of the top selection wheel next to it while watching the LCD panel.

In my hard-back instruction manual its shown in page 78 (section 4).

Use BBF in combination with Servo. Then press and hold for Servo, press and release for One Shot-like operation. Works great in all but very low light, but no confirmation beep.

This is what I was looking for. I hear the MarkIII can do it, but haven't heard if the MarkII can.

Looking at the menus... C.FnIII: Autofocus/Drive → 2 Lens AF stop button function → 4: ONE SHOT↔AI SERVO. This only works with a lens that has the AF stop button though, right?
