Product Description

The dedicated quick-release lens plate for the Sigma 180mm f/2.8 EX DG OS HSM APO Macro is an essential technical asset for close-up, portrait, and precision macro photographers. Because working at high magnifications amplifies even the slightest movement, generic plates that slip or twist will ruin your focal plane alignment, especially under the weight of this substantial f/2.8 macro prime. This custom plate resolves that limitation entirely by incorporating an innovative removable anti-twist ridge. The ridge can be repositioned across multiple locations or entirely removed to conform exactly to the contours of your original lens collar foot, locking your gear square to the plate track.

The standout feature of this plate is its premium double-dovetail profile. This functional geometry creates dual independent clamping surfaces, allowing you to lock the bottom track into your primary tripod head or focus slide while simultaneously utilizing the upper track to mount dual-point macro flash brackets, secondary utility clamps, or accessory arms. The captive-style camera screw slot allows for smooth adjustment while ensuring your mounting hardware stays securely grouped together during transport.

Bespoke-crafted in the USA from ultra-strong aluminum, this accessory provides the structural rigidity required for critical scientific and field work. The low-profile architecture keeps your overall assembly tight and close to the tripod axis for maximum shake reduction. Built with high-grade stainless steel hardware and finished with a durable black hard coat, this lens plate delivers the technical precision and lifelong stability your macro photography workflow demands.
