Arriflex Optex Colcine 2x Teleconverters and power cable

For sale is an Arriflex bayonet mount (not PL) Optex Colcine 2x teleconverter. Will fit Arriflex bayonet mount cameras and lenses or bayonet to DSLR mount adapters. They are probably best suited to MFT size sensors; Panasonic and Olympus CSC camera systems.

Comes with front and rear caps.

This is rare vintage glass from a famous British manufacturer of motion picture accessories that went out of business some time ago.

Also for sale is an even rarer dual Arri S standard and bayonet mount 2x extender, also made by Colcine Optex but has no such engravings.

Additionally, I also have a custom regulated 8.4volt Arriflex S or M power cable.

Earlier Arriflex 16mm cameras with constant or variable speed motors actually ran from a 8.4volt (not 12volt) source. Although the motors will sometimes run from the higher voltage, this strains the internal wiring and will cause the motor to heat up. This regulating cable steps the voltage down from 12volt to the desired 8.4volts.

The cable has the original Arriflex camera plug with a ridge for cameras that were fitted with a cable clamp retainer bracket which stops the cable from being pulled out accidentally.

The asking price is set just to facilitate offers for the individual items.
