UFF-1 Universal Follow Focus is the first follow focus to be compatible with 15mm LW, 15mm Studio, and 19mm rods without the use of adapters. Simply unlock the clamps and slide to the appropriate rod position. Notches in the bottom of the bridge indicate when the clamp is in the correct position.The included swing arm and lens gears can be flipped to the front or back position which is helpful for compact lens configuration and the bridge has the lowest height in the industry so it will work with larger zoom lens barrels.Each of the two hand wheels is compatible with the standard marking disc and hard stop disc which provides positionable limits when using DSLR lenses with infinite barrel rotation. In total, 10 marking discs and 2 hard stop discs are included. The hand wheels are removable and have standard accessory ports for the included focus whip and crank. The crank’s unique design has the same accessory port on the backside which allows the whip to be plugged in when needed.The hand wheel extension allows users to offset either wheel by 75mm (3 inches) which is great when using a large diameter lens or when in 15mm studio mode.Included in the kit are 5 gear attachments:.5 mod for Canon ENG.6 mod for Fujinon ENG.8 mod small diameter for Cinema Lenses.8 mod large diameter for Cinema LensesFriction Gear for DSLR lensesEach kit ships in custom cut foam which fits natively into a Pelican 1500 case (not included).Also available – UFF-1 Universal Follow Focus (Base) for more simple configurations.
