Follow Focus Gear for Konvas OCT-18 lenses (57-86-6mm)

Lenses for turret Konvas (1M, 7M) that have so called OCT-18 mount never had follow focus gears. And there were problems with installing the gears to work on original Konvas cameras due to body shape. But many such lenses are used on DSLR's  and other cameras via adapters now. This makes it possible and even desirable to have follow focus gears on them.

We made such gears. They have industry standard 32 pitch. Weight is 48g. External diameter is 86mm. There are two minor variations - 56mm and 57mm inner diameter. We make 57mm gears ONLY. If you have 56mm lens, you'll need to use thin spacer - foil, for example - to install the gear. Actually, no need in solid spacer - you may use three parts distributed evenly alond the circle.

Also, some OCT-18 lenses may have 59mm diameter of the original focus ring. Pplease check your lens. If it has more than 57mm diameter, we can enlarge the gear bore for you free of charge.

Installation is easy. Three set screws and allen key for them is included. Pictures show installation of the gear onto RO2-2M lens. The lens isn't included into the listing.

Dimensions:

Inner diameter - 57 mm;

Outer diameter -86 mm;

Thickness - 6 mm.

Mod - 0.8 mm (pitch 32).
