Ever since the original Gen 1 Metabones adapters, the factory foot layout has sat exceptionally close to the primary lens axis. Consequently, when trying to lock your camera system onto wide tripod platforms, large monopod tilt-heads, or universal Arca-Swiss quick-release receiver clamps, the bulky barrel of fast-aperture lenses or the horizontal wing of a camera \u003cstrong\u003eL-bracket\u003c\/strong\u003e will physically bottom out against the support hardware. This prevents a clean lock, jams the plate slider slots, and puts dangerous leverage strain on your lens mount.\n\u003c\/p\u003e \n\u003cp\u003e \n    This custom-engineered spacer block provides a permanent, elegant physical fix. Installed directly between the adapter body and your existing plate or replacement foot, it delivers the exact vertical lift required to let wide optics and corner brackets clear your support equipment cleanly. Because close-up macro imaging and telephoto tracking place intense torsional stress on your gear joints, this block is built with precision index tracking channels that seat flush against the hardware. This design choice completely removes stack tolerance errors and dampens micro-vibrations, giving you an ultra-rigid connection that will not slip over time.\n\u003c\/p\u003e \n\u003cp\u003e \n    Bespoke-crafted in the USA from ultra-strong aircraft aluminum, this spacer ensures your optical center remains perfectly squared and true to your tracking axis. The kit includes extended high-tensile fasteners that pass cleanly through the spacer body to ensure deep, maximum-security thread engagement inside the adapter body. Finished with a rugged black hard coat built to withstand severe field use, this spacer block delivers the mechanical precision, safety margin, and lifelong reliability your camera rig requires.\n\u003c\/p\u003e","brand":"Hejnar Photo","offers":[{"title":"Default Title","offer_id":67701614772329,"sku":"Metabones2LB22-x","price":125.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0794\/1278\/9353\/files\/Metabones2LB22-x-2.jpg?v=1792111518","url":"https:\/\/www.hejnarphotostore.com\/products\/metabones-ef-to-e-precision-spacer","provider":"Hejnar Photo","version":"1.0","type":"link"}
