The Nikon FG was introduced in 1982. It was a much improved version of the Nikon EM introduced 3 years earlier. There were many innovative and sophisticated improvements incorporated within the identical compact size camera body. It was Nikon's first multimode AE camera. It was the first Nikon camera that provided a Programmed Auto mode which only required an AI-spec lens to enjoy this incredible benefit. The three exposure control modes available in the Nikon FG are: 

 Programmed AE -  Aperture Priority AE - Manual

To prevent over or under exposure in unusual lighting conditions such as bright seaside shots, black subjects against dark backgrounds or strong backlighting, the FG gives you two ways to adjust exposures on both A and P: the conventional exposure compensation dial (- 2EV +2EV) and the quick and easy one press exposure compensation button (+2 EV).

Before placing a bid on a Nikon FG you find on eBay, be sure the camera is in good working condition.. Read the seller description carefully and ask questions if you have to. Don't waist your time with "needs work" or "sold as is". There are enough of these camera on eBay in good working condition that you should not waist time (and money) on such auctions. Beyond determingin if the camera is in good working order you will also want to consider the following:

1: SEALS: The light seals keep light from sneaking into the film chamber. Even if a camera has never been used, these seals deteriorate over time and need to be replaced. So always ask the seller about the condition of the light seals. If they are worn out they will be sticky to the touch and leave residue on the film chamber door. Ask your seller about the condition of the light seals.

2: FINGER GRIP: These cameras come with a detachable finger grip that makes the camera much easier to cary with. This grip is often missing. You can see what the grip looks like above. Look close to see if the camera you are bidding on includes the finger grip.  

3: VIEW FINDER: Ask sellers if the viewfinder is clear and free of scratches. While this would not affect picture quality it is kind of annoying to see specs of dust and scratches while trying to compose your shot.

I like the Nikon FG. It's compact size makes it easy to carry around and you can purchase compatible lenses on eBay for very reasonable prices. The picture quality is superb. If you can find one in good condition, buy it.
