Precision Calibration for Photographic Lenses

The ARRI MFF-2 HD SLR Hard Stop Set brings cinema-grade operational control to high-end DSLR and mirrorless filmmaking. Photographic lenses often present a challenge for video production due to their short focus rotation and infinite-turning barrels. The MFF-2 HD base resolves this with a tailored 1:1 gear ratio that expands tactile control, while the universal hard-stop knob provides solid, mechanical end-stops for repeatable focus pulls every single time.

Compact Architecture for Lightweight Rigs

Engineered for run-and-gun operations, commercial productions, and compact gimbal setups, this follow focus utilizes a low-profile, single-rod bridge. The tool-less, snap-on clamp slides smoothly onto a single 15mm rod, minimizing weight and keeping camera cages clutter-free. Its adjustable baseline ensures the unit sits perfectly aligned under compact lens bodies without interfering with accessory plates.

Zero-Backlash Durability

Built to the exact standards of professional sets, every component in this kit guarantees absolute mechanical reliability. The reversible gear design lets operators change pulling directions in seconds to match their preferred workflow or specific lens mechanics. Supplied with a standard 0.8 Mod drive gear, this complete system interfaces flawlessly with geared focus rings, providing a fluid, skip-free response under demanding field conditions.
