The K&F Concept adapter from Nikon F to Nikon Z allows for the precise attachment of Nikon F lenses to Nikon Z camera bodies. This mechanical adapter retains full exposure automation functionality but requires manual aperture and focus adjustments, as autofocus is not supported. The adapter works effectively with lenses that have built-in aperture rings, enables focusing up to infinity, and preserves optical quality. Made from brass and aluminum, this adapter offers stable, precise, and durable performance with accurate tolerances for reliable lens-camera connections. Compatible with all Nikon Z cameras, including Z6, Z6 II, Z7, Z30, and Z9 models, the adapter measures approximately 25 mm in length with a diameter that matches standard lens mounts. The black anodized finish ensures corrosion resistance and a professional appearance. Weighing about 85 grams, the adapter maintains compact dimensions while providing robust construction. This adapter solution allows photographers to use their existing Nikon F lens collections with current Nikon Z mirrorless camera systems, preserving lens functionality and adapting to modern camera bodies. The machined brass mount ensures a secure connection with minimal play, guaranteeing consistent performance under various shooting conditions. The aluminum housing construction offers lightweight durability without compromising structural integrity. The adapter maintains the correct flange distance for accurate focus calibration, supporting both manual focus operation and exposure metering systems. This precision tool serves photographers who need compatibility between traditional F optics and contemporary Z camera technology.
