use with rebel xsi, mr-14 ring flash, aperature at 29 or 32 and shutter speed 1/60. get great depth of field and incredible detail
takes great before and after photos of patients teeth; When I put patients pictures up on the screen, I can zoom in on the smallest detail and patients can clearly see and understand what I see; The smallest details are clearly obvious.
will sometimes hunt for focus; but I manual focus anyway
