2.00" U-Shape Modular Lens Support for External Focusing and Variable Length Lenses

The Hejnar Photo 2.00-Inch U-Shape Modular Lens Support is a specialized stabilization solution specifically engineered for lenses with external focusing mechanisms and barrels that change length during focal adjustments. Featuring a unique U-shape supporting bar and 1.150-inch diameter wheels, this system allows the wheels to rotate parallel to the lens barrel. This ensures constant, friction-free support even as the lens extends or retracts. Proudly CNC-machined in the USA from solid 6061-T6 aircraft-grade aluminum, it provides the essential stability needed for technical and macro photography.

SAE Technical Specifications

• Rail Length: 2.00 inches.
• Wheel Diameter: 1.150 inches.
• Support Bar Style: U-Shape (parallel rotation design).
• Application: Optimized for external focusing and "telescoping" lens barrels.
• Material: CNC-machined solid 6061-T6 Aircraft-Grade Aluminum.
• Finish: Black hard-coat anodized for superior abrasion resistance.
• Manufacturing: Designed, machined, and quality-tested in the USA.

Quick Overview & Key Features

• Parallel Wheel Rotation: Specifically designed so that the 1.150" wheels track with the movement of the lens barrel, providing continuous support during zooming or focusing.
• Eliminates Lens "Jump": Prevents the common focal shift and vibration that occurs when variable-length lenses are used without proper front-end stabilization.
• Modular Stability: The 2-inch Arca-Swiss compatible rail base allows for seamless integration with our standard multi-purpose rails and clamps.
• Protects Camera Mounts: Removes the leverage stress from the camera's bayonet mount by establishing a rigid, moving secondary point of contact.
• Universal Arca Standard: Fully compatible with quick-release systems from RRS, Kirk, Wimberley, and Markins.

Detailed Product Description

The Hejnar Photo 2.00-Inch U-Shape Modular Lens Support is the definitive answer for photographers using lenses that physically expand or contract. Standard cradle supports are designed for fixed-length (internal focus) lenses; using them with an external focusing lens can cause binding or uneven pressure. Our U-shape architecture reorients the 1.150" wheels so they roll with the lens, maintaining a perfect, friction-free crutch regardless of the focal length setting.

This system is particularly critical for macro photographers and those using long telephoto zooms where the front element extends significantly. By establishes a dual-point platform—your tripod foot and this moving roller support—you effectively eliminate the "telescoping sag" that often compromises image sharpness. The 1.150-inch wheels are sized to offer high stability for medium to large barrel diameters.

Machined from solid blocks of 6061-T6 aircraft alloy and finished with a durable hard-coat anodize, this USA-crafted component is built for the rigors of field use. It offers the same precision and structural integrity that industry leaders expect, combined with the specialized modularity that allows your gear configuration to adapt to any moving optics setup.
