I have a Petri FT that my grandmother gave me, and I was hoping that somebody here could help me out with it. I don't really know much about old cameras or how to use them. I'm interested in trying it out, maybe attempting some star trail photography, if it is capable. I don't really know the condition of it, it appears to be in good shape, but I haven't tried to use it since I'm not familiar with this kind of camera and didn't want to risk messing it up. Any help would be appreciated.
