Adding to bag… The item has been added


A replacement foot with built-in-dovetail mounting will be lighter, lower in profile, and provide the best possible stability for your lens. Really Right Stuff foot replacements are precision machined from solid blocks of 6061-T6 aluminum and are fully compatible with our 1.5" RRS Dovetail Standard. This foot replaces the Nikon foot on the Nikon Z 70-200mm f/2.8 VR S lens, Z 100-400mm f/4.5-5.6 VR-S, Z 400mm f/4.5 VR S, or Z 600mm f/6.3 VR S.  NOTE: We are not aware of any camera or telephoto converter that will not balance properly with this foot. In some cases you will have to make full use of the dovetail to move the camera/lens forward in the clamp. Please contact us if you have any specific questions.

    The LCF-21 replacement foot is of high quality as all of the products from RRS. This foot will fit perfectly on the new Nikon Z 600mm F/ 6.3 lens.
