Just got my GH2 yesterday. I've been reading these forums for about a week and I've gotten very excited about the possibilities of legacy glass. I especially wanted to pick up a good, fast 50mm lens. After combing the local Craigslist listings, I drove about an hour to buy a 1974/5-era Nikon Nikkor 50mm f1.4 lens (pre-AI). I paid $40 for it. To my novice eye, it looks to be in excellent condition. The guy I bought it from said that his father (the owner of the cameras and lenses for sale, now deceased) did not really use that lens. It was the kit lens I guess, and he took it off the body and used a 200mm lens preferentially for his work. The lens seriously looks brand new ... no signs of wear, no scratches on the body or the glass, and the blades look clean. The lens had a filter on it (which actually looks in really good condition as well). Everything turns smoothly. Of course, I don't have the F-mount adapter yet (just ordered one) so I haven't been able to take any shots with it, but I'm looking forward to it. It seems a crime that I'll have to pay about 70% of what I paid for what appears to be a fabulous piece of glass, to buy a cheap adapter made of aluminum in order to use it!!
