I have a nice point and shoot (Sony cybershot DSC-H7) and I since I bought it my interest has only increased. Now I want a dslr in the future. My mom had an older film slr with only one lens The battery will need replacement, it needs to be cleaned and there is one section in the back that lets in light (which is why it is currently covered with electrical tape.) But, my mom fully believes it will perform fine with some touching-up put in it. It is a canon ftb. I believe it was one from the first two years of production. I know they made some revisions in 1973 but I don't seem them on this camera. Is anyone familiar with this camera or have any tips I could use?
