Newest franken-lens has the optic (22/2.8) from a
Minolta 16-II and C-mount/focus assembly from a junked pentax CCTV fisheye that came out of a bin for essentially free. Using a C-mount adapter. Focuses from infinity to 10 inches, and can get that down to two inches by partially unscrewing the optic from the focus assembly.
The goal was a carry-around lens flatter than the grip on the camera body. Thanks to the focuser I scavenged, that goal wasn't quite met. I'll be trying a different one most likely. It also still needs some flocking/baffling inside.

A sample taken with the lens:
Yes, that's a film canister in her hand. She was pretending it was a bottle for a stuffed panda, and yelling "CHEESE" at me.
The quality is about what I expected, maybe a bit better than I hoped for. Minolta was capable of good work, and they did put some effort into this more capable end of their subminis (the ones with actual aperture adjustments and such). It doesn't have a thoroughly "classic" signature like, say, some of the old Russian lenses or old Leica/Zeiss stuff. But it is nicely gentle for portraits and general environmental stuff. That said, at its current size it doesn't have much advantage over either the 20/1.7 or the 17/2.8 except price. Which isn't inconsequential when you have little kids and aren't rich, but we're talking about a difference when all is said and done of a couple hundred bucks, not thousands, so.
Edit to add: this was inside at night hand-held at 1/25 with the wrong stabilization setting dialed in. It is capable of better sharpness than is on display here but there are limits.
