This picture was taken with a Tamron 24mm f/2.5 adaptall lens. The copy I have looks very ugly with the rubber focusing ring about to fall out. The overall cosmetic condition is, well, disgusting. BUT, this little lens is very sharp for a 24mm! With a KA adapter, this lens will act as an A lens on the DL, meaning that all program modes are supported.

One of the best features of this lens is the very close focusing distance. It can focus as close as 10 inches, as close as some macro lenses.

Despite its age, this well design lens really lives up to its SP designation. It's a great companion to my SP 90 f/2.5
