Metabones Z-Foot System with 4" Arca-Swiss Base Plate | Lens Balance Support

The Hejnar Photo Metabones Z-Foot with 4-Inch Base System is a professional engineering solution custom-designed to bring balanced, telephoto-style functionality to adapted lens setups. Comprising a specialized Z-shape vertical support foot and a dedicated 4.00-inch Arca-Swiss compatible base rail, this full assembly replicates the handling of a native tripod collar. By shifting the primary mounting point forward away from the camera chassis, it drastically optimizes weight distribution, relieves stress on the camera mount, and enhances tracking stability on tripods, monopods, or gimbals.

Quick Overview & Key Features

• Telephoto Collar Functionality: Bridges your camera body and Metabones adapter to support the system from the lens axis, transferring structural weight off the camera's bayonet mount.
• Optimized 4.00" Travel Rail: Generous extended base provides a broad fore-aft adjustment zone to fine-tune your center of gravity and balance diverse gear setups.
• Adjustable Vertical Positioning: Advanced modular geometry allows the vertical Z-foot component to be mounted in different physical positions along the base rail for customized balancing.
• Universal Arca Dovetail Profile: Integrated Arca-type track on the base ensures a flawless, zero-play lock inside standard quick-release clamps from RRS, Kirk, Wimberley, and Leofoto.
• Anti-Twist Alignment Channels: Precision-milled geometric seating slots completely eliminate rotational slipping or mechanical play under heavy torque loads.
• Premium Construction & Finish: Precision CNC-machined in the USA from solid 6061-T6 aircraft-grade aluminum and finished with a resilient black hard-coat anodized layer.
• Heavy-Duty Hardware: Packaged with high-tensile, corrosion-resistant stainless steel mounting screws built to withstand rigorous outdoor field use.

Product Description

The Hejnar Photo Metabones Z-Foot with 4-Inch Base System solves a critical balance and stabilization bottleneck commonly faced by wildlife, sports, portrait, and cinematic shooters deploying adapted lenses. When non-collared telephoto zoom or heavy prime lenses are attached via an adapter, the entire structural weight is suspended directly off the camera body mount. This rear-heavy geometry results in severe nose-diving on tripods, restricts smooth fluid tracking on gimbals, and introduces unwanted micro-vibrations that can compromise image sharpness during long exposures.

This advanced system resolves that physical limitation entirely. By integrating the Z-shape vertical support foot directly onto the custom 4.00-inch base plate, your configuration transforms completely. The layout acts exactly like a traditional telephoto lens foot collar, shifting the physical weight support point forward into a perfectly neutral position. To adapt seamlessly to varying equipment builds—such as adding a heavy battery grip or using unique lens hoods—the vertical portion of the Z-foot can be unbolted and repositioned across different locations along the base plate axis, allowing for a fully custom-tailored weight distribution.

Bespoke-crafted in the USA from ultra-strong aircraft aluminum, this low-profile base rail eliminates structural flexing while keeping your center of axis tight to the tripod head for maximum stability. The bottom features a flawless Arca-type dovetail profile that slides smoothly into professional receivers without slop. Finished with a rugged black hard coat built to withstand field transport scuffs and paired with robust stainless steel fasteners, this complete assembly delivers the technical precision and lifelong tracking stability your photography workflow demands.
