Because panning and tracking fast-moving subjects puts immense rotational force and twisting pressure on your camera support train, generic universal single-screw plates can easily slip or spin out of square on the tripod foot. This custom plate completely resolves that physical vulnerability by deploying a dedicated \u003cstrong\u003eanti-twist locating pin assembly\u003c\/strong\u003e. By capturing both the primary 1\/4-20 thread and the factory indexing hole simultaneously, it forms an unyielding connection that guarantees absolute tracking squareness.\n\u003c\/p\u003e \n\u003cp\u003e \n    The generous 3.00-inch total rail length provides a useful fore-aft travel adjustment window inside your tripod head quick-release clamp. This structural track lets you shift your camera package smoothly back or forth to locate a perfect neutral center of gravity on a gimbal node or ball head, which helps eliminate front-heavy nose-diving and dampens focal micro-vibrations for sharper long-exposure captures. For maximum versatility, the alignment pin is completely modular and can be removed or relocated if you wish to adapt the plate profile to other traditional telephoto lens collars that rely solely on flat surface friction.\n\u003c\/p\u003e \n\u003cp\u003e \n    Bespoke-crafted in the USA from solid aircraft aluminum and packed with professional fail-safes, this lens plate is engineered to survive and perform across punishing outdoor assignments. The low-profile cylindrical screw head houses a deep, precision-milled internal drive socket that accommodates standard hex keys, allowing you to deliver massive manual leverage for a permanent lockup. Finished with a rugged black hard coat built to withstand field transport scuffs, this accessory delivers the technical precision and lifelong field reliability your high-end optics deserve.\n\u003c\/p\u003e","brand":"Hejnar Photo","offers":[{"title":"Default Title","offer_id":67701593669737,"sku":"D033","price":45.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/1278\/9353\/files\/D033-2.jpg?v=1792110785"}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/1278\/9353\/collections\/D033-2.jpg?v=1792635051","url":"https:\/\/www.hejnarphotostore.com\/collections\/lens-plate-for-pentax.oembed","provider":"Hejnar Photo","version":"1.0","type":"link"}
