Testing the quality of my film camera’s lens

I recently found out that the 50mm standard lens on my film Pentax, a ProgramA, could be put onto my K-r’s body. There wouldn’t be autofocus, but as long as I was prepared to manually focus I could use the lens and it would do the aperture movement dance happily.

I was overjoyed, but needed a clear, sunny day to try out the lens to see if it is crisper than the kit lenses that came with the camera.

The chances are good that the lens would be, but it’s nice to be sure.

Weeks went by with just endless gray clouds for sky cover, but eventually one such clear day did emerge.

I took off to Norton Summit Road to shoot an old burnt tree I had spotted a week or so before.

I didn’t do a direct comparison with my kit and 50mm lens, which I know I should have, because I was short of time, but just looking at the result from the 50mm lens (which is the equivalent of a short telephoto 75mm on my K-r) I feel confident that the 50mm lens is slightly sharper and crisper.
