Lens adapter enabling Kiev 10/15 lenses to mount on Sony E-mount cameras with infinity focus and aperture control through a simple 20-degree lens rotation. Compatible with both early and A7II series E-mount versions. Using the adapter: Although the adapter was designed for the newer A7II-style E-mount, it also works on the original mount (e.g., the original A7 shown in the above photo), but with a tiny bit of play. Bayonet the lens into the adapter before mounting the adapter on the camera. Also watch for, and remove, any plastic shaved off the Kiev 10/15 mount by the lens: this shouldn't happen after the first few times, but being careful is easier than cleaning shavings out of your camera body. The aperture adjustment is made by rotating the lens slightly in the mount; a little hook catches the internal lens aperture coupler. Be sure to hold the adapter, rather than the camera, when turning the lens in the adapter. Also be careful not to turn the lens enough to dismount it... there is no locking mechanism on this adapter. Only printed parts, hardware NOT included.
