OCT-18 lens to Arri PL camera mount adapter for zoom lenses, black

This adapter can be used to install LOMO (Lenkinap, KMZ) lenses with OCT-18 mount (for turret Konvas) onto cameras with Arri PL mount. It allows infinity focus.

Take note that this is a simple adapter - it holds the mount of the lens so it can't rotate. This means that it fits zoom lenses (Foton, Lenar, OPF series) since these lenses have a focusing mechanism independent from the mount.

On the other hand, most of OCT-18 primes need to rotate in the mount to focus properly. Actually, you can still focus them even using such a simple adapter, but the lens behavior will change in this case - the focus ring will become immovable, and you'll have to turn the optical block for focusing, that is not very convenient. Also, you'll be able to focus closer than 1m - but with risk to unscrew the optical block from the focusing mount completely.

So, once again: this adapter suits OCT-18 zooms perfectly. Using with primes is possible with some issues.

For sale is the adapter only with corresponding hex key to secure it on the lens mount with three grub screws. The lens is shown for illustrative purposes only.
