DOF and closeup lenses
I have just bought a Minolta 7i and this weekend I set up some tests (Both inside with natural light and outside) to check the DOF. I set the camera lense at 50mm, Aperture Priority, and used all of the aperture settings from 3.5 to 9.5. I didn't find much difference in the DOF. Someone told me I could get a shallower DOF by using closeup lenses. Is this the best way or am I doing something wrong with my camera?
