Tilta - Nucleus-M II Extended Mod Motor Gear

The Tilta Nucleus-M II Extended Mod Motor Gear is a precision-engineered replacement gear designed specifically for the Nucleus-M II wireless lens control system. This essential accessory resolves a common pain point for cinematographers: physical interference between the lens barrel and the follow‑focus motor gear. By increasing the gear’s diameter, the Extended Mod Motor Gear extends the motor’s reach, allowing it to clear bulky or uniquely shaped cinema lenses that would otherwise be incompatible. Whether you are shooting with anamorphic glass, vintage optics, or modern cine lenses with short gear ring clearance, this simple upgrade unlocks a wider range of lens choices for your storytelling.

Key Features
Specially Designed for Nucleus-M II Motors – Engineered exclusively for the Tilta Nucleus-M II wireless lens control system, ensuring a perfect fit and seamless integration.

Wider Diameter for Increased Clearance – The extended diameter allows the motor to reach farther, eliminating physical interference between the motor gear and lens components.

Broader Lens Compatibility – Enables the Nucleus-M II motor to attach to a wider variety of cinema lenses, solving incompatibility issues that arise from unique lens designs.

Easy Installation – Swaps out the standard gear in seconds using a simple flathead screwdriver. No specialized tools or technical expertise required.

Durable ABS Plastic Construction – Lightweight yet robust, the black ABS plastic gear withstands the demands of professional filmmaking environments.

Compact and Lightweight – Weighing just 0.18 lb (approximately 82 g) with dimensions of 4.7 × 3.5 × 2.8 inches, the gear adds negligible bulk to your rig.

Use Cases

Anamorphic and Large‑Barrel Lenses – Many anamorphic and modern cinema lenses have wide barrels that crowd the follow‑focus motor. The extended gear provides the extra clearance needed to keep the motor out of the lens’s way.

Vintage and Hybrid Optics – Older lenses and hybrid photo‑cine optics often feature non‑standard gear ring placements. This accessory ensures your Nucleus‑M II can drive them reliably.

Gimbal and Compact Rigs – When space is at a premium, every millimeter counts. The extended gear allows you to position the motor farther from the lens without changing your rod setup.

Studio and Handheld Configurations – In multi‑motor setups (focus, iris, zoom), the extended gear prevents adjacent motors from colliding, keeping your workflow smooth.
