Kiev 10/15 Lens To Sony A7II-series Body Adapter

myminifactory

The Kiev 10 was a pioneering Soviet-built 35mm SLR that boasted automatic exposure, achieved through an ingenious internal linkage connecting the body directly with the lens aperture. This innovative design eliminated the need for an aperture control ring on the lens itself. The same lens mount used by the Kiev 10 was also employed by the Kiev 15 TEE, however, nothing else shared this feature, and the internal aperture linkage posed significant challenges when adapting to other mounts. In a previous tutorial, I revealed a method to hack an adapter, allowing for Kiev 10/15 lenses to be mounted on digital cameras with aperture control, albeit in an awkward manner. The adapter showcased here offers a more practical solution, enabling Kiev 10/15 lenses to seamlessly mount and focus at infinity on Sony E-mount bodies while providing precise aperture control through a mere twist of the lens – much like my earlier design, Thing 137540. Sony's E-mount comes in two distinct variations, with the newer version being tighter, making adapters designed for the first not necessarily compatible; this adapter is specifically engineered to fit the latter version, as used by A7II series cameras, and also accommodates the earlier version with minor play.
