The Kiev 10 was the first Soviet-built 35mm SLR with automatic exposure. It did this using an internal linkage for the body to control the lens aperture -- there is no aperture control ring on the lens. The same lens mount was used by the Kiev 15 TEE, but nothing else, and the internal aperture linkage makes adapting to another mount problematic.
Thing 1464062 is an adapter I designed to mount these lenses directly on Sony E bodies, allowing a slight turn of the lens to adjust the aperture. This adapter is very similar (on the Kiev 10/15 end), but adapts to Leica M body mount. Why? To use these manual lenses with autofocus on the latest Sony E bodies via the Techart Pro LM-EA7 adapter!
The last two shots were taken using the LM-EA7 autofocus on an A7II with a Jupiter 9.
A very straightforward print. I used "dishwasher safe" high-temp black PLA. It should be a little tight, so work a lens in the mount a bit before attaching to a camera -- that way, you can clean any little shards that the flange might cut the first time you fit a lens to it.
For those who have looked at Kiev 10/15 lenses, the obvious issue is that they don't have aperture rings... so how do you adjust the aperture given that this adapter has no moving parts?
It's very simple: you turn the lens slightly. The lens mounts with a fairly extreme rotation, but doesn't lock. Once you've rotated it into place, there is a little nub on the inside that will catch the internal aperture control lever on the back of the lens mount. Then turning it slightly opens/closes the aperture... no markings, but still very usable.
