[OFB Cafe] Photographers?

[Donald R Spoon]

Back in the mid 1970s I collected some lenses for my Pentax 35mm SLR 
camera.  I have a big zoom (out to 210mm IIRC) and another smaller one 
that does macro stuff, I think.  I know for sure they were screw mount 
for the Pentax camera body.

Anyway, can anybody tell me if they would work on any modern Digital 
cameras?  If not, is there any market for any of that old 35 mm SLR 
stuff?  I know I am not giving very specific info, but I would have to 
dig through a couple of moves worth of boxes to find them...

Cheers,
