This question already has an answer here:
I'm sure these kinds of questions are asked all the time but is it possible to mount an old SLR lens like this on a newer DLSR camera? The Tokina lens is made for a Pentax K1000 and I have a Nikon D3300. I've also got a Canon FD 70-210mm zoom lens but I read online you can't use those with DSLR bodies. Does anybody know where I could find an adapter for these lenses, if they're even compatible? Any info would be appreciated.
