The included parts within the Ncam Mk2 External Encoders kit consist of 0.5, 0.6 & 0.8 pitch gears which can be removed and replaced using the supplied screw driver.

Also included are 15mm & 19mm Encoder mount arms for use with mounting rods.

For Broadcast lenses the mount already attached to the encoders can be screwed directly onto the lens barrel. Example images can be found below.

Any lens that you wish to use with external encoders must have a physical stop at each end of the movement of the lens barrel. Most DSLR lenses for example have a focus barrel that can spin continuously

The lens must have 0.5, 0.6 or 0.8 pitch gearing on the barrel for the external encoders to correctly connect with the lens

The Mk2 external encoders are only compatible with the Mk2 platform

External encoders must be homed when using them with the system, this process is described in the lens homing section
