Yes, perhaps I meant, " is LIKE the view gotten from a 28mm lens made for full format 35mm film". Thank you for the correction Ricardo.
Here are two photos of the lens, as well as a photo that the lens took out of my window at the smallest aperture (by default), which I would estimate at f32. The fire escape window in my efficiency provides three uses: 1) an escape from fire, 2) a portal to feed the pack of chickadees who park there, on cue, each morning, to be fed bits of whole wheat bread, and 3) an ideal 'infinity focus view' that I use when I need to check focus.
The print is razor sharp, no matter what the distance. Diffraction did not seem to be an issue here, despite using a tiny aperture at full wide angle. (Thus, would it be yet sharper at f8?) Perhaps my digital Canon "S2 IS" did not do justice to the 5X7 B&W print. But... is there a bit of barrel distortion? Very dreary weather.
NOTE BENE: You know, the reason I guess I posted this in the 'repairs' section is because I had removed the front part of this lens to fix the focus: it was smooth until about 10 feet, then it was stiff from 10 feet to infinity. Turns out that it was only a piece of broken plastic near the helicoid that was providing a barrier and was easy to remove. - David Lyga
