Camera focus

What can cause the focus to work poorly?

It all depends on the camera you are using. For example, in Canon, there is a canon back button focus . Back button focus is a shooting innovation that has detached focus from the shutter and put them into their own individual camera buttons. Back button focusing is all about performance and reducing focus errors. By activating it, you will say goodbye to refocusing, extend your battery’s life and get rid of focusing errors forever. Back button focus stops focusing when something might go wrong and interrupt shooting. It is excellent while shooting moving objects.
