D850 Camera Back Button Strip Zoom OK

Replacement rear control strip for Nikon D850 DSLR, containing Zoom In, Zoom Out, Unlock and OK buttons in authentic configuration. Constructed from durable ABS plastic with fine-grain surface texture for grip and wear resistance. Thickness and curvature match OEM design to ensure proper flex cable contact pressure and eliminate rattling behind rear cover. Compatible only with Nikon D850 — verified against service manual diagrams and physical teardown benchmarks. Includes no additional hardware; relies entirely on stock rear cover retention system. Colour appearance may vary slightly due to lighting and display settings — actual part is consistent in form and function across all batches.
