My dad recently gave me 3 older cameras of his, two SLR 35mm cameras and a TLR (but I want to hold on to that one, it looks cool). I have a Minolta X-700 with a 50mm lens and a Nikon FG with a 28mm and 135mm lenses. I know that these particular cameras are about 20 years old (I think?), but are they worth anything? I was thinking of trying to sell them to buy a DSLR, but was wondering if some of you guys who know more about this could tell me if I should try and sell or just hold onto them and save up for the DSLR. Thanks in advance for any help on this!
