The Nikon FG is a small SLR from the early 1980′s similar in size and function to the Olympus OM-1 and the Pentax ME. Like those cameras this camera is manual focus. It does provide a programmed exposure mode as well as aperture priority and full manual. The shutter is electronically controlled so it requires batteries to operate with the exception of 1/90 second and bulb which are mechanical. What the Nikon has over the other two is control over exposure. In addition to the PAM modes it has +-2 stops compensation in half stops and a +2 backlight compensation button. I feel this is a great choice as a compact SLR for anyone wanting to shoot film in addition to digital.
