Lens Mount Adapter K&F SB10104 — Nikon Z (Z-mount) to Nikon F (Nikkor Ai/Ai-s/Af/Af-s) mount

The K&F SB10104 lens mount adapter enables photographers to mount Nikon F-mount lenses (Nikkor Ai, Ai-s, AF, AF‑S) onto Nikon Z-mount mirrorless cameras. This mechanical adapter preserves the physical connection between legacy and modern F-type lenses and Z bodies, allowing manual focus and aperture control where the lens supports those functions. It is built to provide correct flange distance adaptation so that F-mount optics can achieve infinity focus on Z cameras.

Advantages

The adapter offers solid mechanical alignment and a metal construction designed for stable lens attachment and repeatable positioning. It allows the use of a wide range of F-mount lenses without electronic communication, making it compatible with many manual and autofocus lens types in a passive way. The SB10104 keeps the optical axis and flange distance consistent for accurate focusing and preserves the mechanical aperture linkage where present on the lens.

Suitable for

• Photographers using legacy Nikkor Ai / Ai‑S lenses on Nikon Z mirrorless bodies
• Portrait and landscape photography with manual-focus optics
• Creative work requiring older lens characteristics, such as unique bokeh or color rendering
• Adapters for studio, travel, and educational setups where lens interchangeability is needed

Key specifications

• Mount type: Nikon Z camera side to Nikon F lens side (mechanical)
• Compatibility: Nikkor Ai, Ai‑S, AF, AF‑S F-mount lenses
• Construction: metal mount body for durability and alignment
• Functionality: passive adapter without electronic contacts; manual aperture and focus control as supported by lens
• Flange distance compensation: designed to maintain correct infinity focus when using F-mount lenses on Z bodies

How to use

Attach the adapter to the Nikon Z camera by aligning the index marks and turning until it locks in place. Mount the F-mount lens onto the adapter by aligning its mounting mark and rotating until it clicks. Set the camera to allow manual lens operation or to focus in manual mode if required. Use the lens aperture ring or camera controls (if the lens supports electronic aperture coupling) to set the desired aperture, and focus manually using the camera’s focus aids such as magnification or focus peaking.

Usage recommendations

For reliable results, verify mechanical fit and secure attachment before each shoot. Use manual focus aids on the Nikon Z camera for precise focusing with adapted lenses. When using autofocus F-mount lenses, expect limited or no autofocus performance because electronic communication is not provided. Clean mounting surfaces and keep the adapter away from abrasive debris to maintain alignment and prevent wear.
