|I've got a tiny Elgeet lens with an indication of maximum aperture on the barrel which is f2.3. No other indication of the focal lens or further aperture values is given. The resulting image gives a focal of around 35mm.
The lens has a small aperture lever, I presume intended to couple it with a distant adjustment lever. The mount is absent, it is a round plate with three holes. The lens itself is screwed into a small cage that allows focusing. Everything shows it was in technical use, kind of airplane or surveillance camera.
The lens barrel is as small as 22.5mm in diameter. The flange distance is also small, I had to put it on Nex-M39 adapter with a custom ring and some scotch, and make it recess into the adapter to reach infinity. I was wondering the quality (sharpness), but first of all the image circle.
It does not cover FF, but works with APS-C giving quite a special, not swirly, but rather interesting OOF out of center.
#1 Put on Sony A7, wide open
#2 On Sony A7 switched to APS-C mode, with the diaphragm slightly closed
#3 Close range, the diaphragm the same way slightly closed
#4 It's interesting how fast the image portions go OOF giving this special fuzziness, pleasant at my taste
#5 Freelensing w/o macro taken on Nex (a detail of a wooden chair)
The lens is not sharp w/o, nor particularly sharp closed down a bit. It's more a special effect instrument, with its character to render out of center portions of the image. I ask myself it it might really be used in air photography, or it's another kind of optics.
If someone is interested, I will take a shot of the lens itself and will post it here.
