This custom accessory seamlessly transforms your factory lens foot into a native Arca-Swiss component, providing a rock-solid connection to your tripod head that completely eliminates the unwanted vibrations, flex, and play associated with generic universal mounting adapters. The 3.00-inch rail length is meticulously chosen to provide a generous fore-aft adjustment travel range, allowing you to fine-tune your center of gravity and achieve a perfect neutral balance on gimbal nodes or fluid heads when paired with varying mirrorless camera bodies.\n\u003c\/p\u003e \n\u003cp\u003e \n    Security and equipment protection remain paramount in this design. By combining a premium captive-style stainless steel 1\/4-20 screw with a dedicated mechanical anti-twist registration pin, the plate locks onto the G Master lens foot with extreme stability. This structural layout resists heavy rotational leverage, keeping your camera setup aligned square to the tracking track even during rapid transitions between landscape and portrait panning configurations. \n\u003c\/p\u003e \n\u003cp\u003e \n    The utility is further enhanced by the inclusion of an integrated, heavy-duty \u003cstrong\u003estrap loop socket channel\u003c\/strong\u003e. This built-in slot allows you to lace and secure your favorite ergonomic wrist strap, hand sling, or field safety tether directly through the unibody of the plate. By opting for a traditional configuration without bulky push-button sockets, this plate maintains a clean, ultra-smooth build that glides effortlessly through tight clamp receivers. It eliminates deep pocket cavities, ensuring an ultra-low profile that won't catch on gear bag divider slots. Precision CNC-milled in the USA from solid aluminum and packed with professional fail-safes, this lens plate delivers the technical precision your mirrorless photography demands.\n\u003c\/p\u003e","brand":"Hejnar Photo","offers":[{"title":"Default Title","offer_id":67701623259241,"sku":"SLP-003","price":50.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/1278\/9353\/files\/SLP-003-2.jpg?v=1792111673","url":"https:\/\/www.hejnarphotostore.com\/products\/sony-100-400-arca-plate","provider":"Hejnar Photo","version":"1.0","type":"link"}
