It is a rather old piece of equipment, in very good condition. Manual aperture, shutter speed, film speed etc, all very nice But what should i do with it? I have no experience with this, and was wondering if i should keep it and give it a go, or sell it and get something else to add to my current equipment? I was also given an EOS1000 and a sigma 35-135mm lens..... I am a nikon user so sell and keep the lens?
