The Genus Pitch Gear (0.8mm) is used with the Genus G-SFOC Superior Follow Focus to ensure precise focusing of lenses. Equipped with a large diameter (0.8mm), the pitch gear can be easily attached to the flexible lens gear without touching the lens housing. It is ideal to be used with wide lens barrels.

Obviously this doesn't actually have a diameter of 0.8mm as stated in the description (apparantly an error passed down directly from Genus), so I bought this HOPING that the diameter was significantly larger than the stock Genus gear. Luckily it WAS!! It's approx 45mm in diameter and 11mm thick, so it elimitates the problem of the FF housing bumping up against the lens when using the stock (and way too small) focus gear. It fits perfectly into the FF axle shaft and works like a charm on my Genus "Superior" model FF.
