Hello all, I'm new to the forum, and I'm looking for a little advice on a new camera to get. I'm an amateur and will use it only for artistic purposes. I'm hoping to spend around $300. I don't really have any brand loyalty, it's just hard to know where to start looking. I currently have a couple cameras that were given to me: they are old Pentax Spotmatic F, and I have about four lenses that fit them (they say Asahi Takumar on them). are these worth anything? Is there anyway I can adapt these screw-type lenses to the new bayonet type cameras? thanks for the help.
