Product Description

The Hejnar Photo 3.75-inch lens plate is an original design created for photographers who need a reliable Arca-Swiss mounting surface without the constraints of a fixed anti-twist ridge. Its flat-top design makes it an exceptionally versatile choice for various lens collars, telephoto zooms, and camera bodies where a ridge might interfere with the mounting footprint.

The plate features a captive-style slot that provides smooth travel, allowing you to fine-tune the nodal point or balance of your equipment on a tripod head or gimbal. Additionally, the integrated 1/4-20 tapped hole serves as a convenient mounting point for accessories like flashes, microphones, or secondary support arms directly on the plate without needing extra clamps.

Safety and stability are central to the design. The double-dovetail profile provides a secondary clamping surface on the top side of the rail, perfect for specialized rigs or flash brackets. Precision-machined in the USA from solid aircraft-grade aluminum, this 3.75-inch rail (95.25mm) is built for a lifetime of professional performance and weighs only 1.6 oz.
