Back Focus is a mechanical adjustment for focusing a camera. It moves the image sensor in relationship to the lens to allow for different back focal lengths of lenses. This is important when fitting a zoom.
The customer service received was exceptional! Efforts to assist with product satisfaction were more than expected - personnel assisted me in an effort to ensure products functioned correctly and offered support in product operation!
