It looks like you can use the back button to focus but also the shutter button. With the 60D if you enabled the back button to focus, it disabled the shutter button to focus. What is the advantage of this?
There isn't much advantage to having focus on both buttons, like a lot of modern cameras there are two separate settings necessary for proper back button focus, one enables the back button the other removes focus from the shutter button, Search through your cameras menu and you will find them.
is the main idea / advantage of back button focusing so you can shoot once you have focus without the camera trying to re focus?
The main idea is that you take your time and focus first and then maybe recompose and then you press the shutter when you are ready. Works for me on all four cameras.
ok, think i been doing that in a way on some pic, been using the normal shutter button as it came (M50) on auto focus then if i wanted to recompose i hit the manual focus button to temporarily disable the auto focus on the shutter button and take pic.
hello, Susan. I have a 60D and have the rear button set up for back button focus and the shutter button activates the shutter, I suggest you have a look at your manual and reset it up or there are some informative video clips on you tube that should help.
