Lens Mount Adapter Pixco for NIKON (Ai/AiS/AF) to CANON EOS (EF/EF-S) — Pixco SB1699

The Pixco SB1699 lens mount adapter enables the physical use of NIKON Ai, AiS and AF lenses on Canon EOS cameras with EF and EF-S mounts. This mechanical adapter maintains correct flange focal distance to allow manual focusing and aperture control from the lens. It is intended for photographers and videographers who want to combine Nikon optics with Canon camera bodies while retaining full mechanical connection for aperture blades and reliable lens mounting.

Advantages

The adapter provides a sturdy mechanical connection between Nikon F-mount lenses (Ai/AiS/AF) and Canon EF/EF-S camera bodies without electronic communication. It preserves lens flange spacing to enable accurate focus at infinity and supports manual aperture adjustment on lenses that have mechanical diaphragms. Its compact metal construction ensures stable mounting and repeatable alignment when changing lenses, making it suitable for both still photography and video recording.

Suitable for

• Photographers who own Nikon Ai, AiS or AF manual and autofocus lenses and want to use them on Canon EOS bodies
• Videographers seeking the optical character of Nikon lenses on Canon mirrorless-adapted DSLRs or crop-sensor EOS cameras
• Lens collectors and hobbyists experimenting with cross-mount lens combinations

Key specifications

• Mount conversion: Nikon F (Ai/AiS/AF) to Canon EF/EF-S
• Construction: mechanical, passive adapter without electronic contacts
• Material: metal alloy mount for durability and stable connection
• Flange distance preservation: maintains correct register for manual focus and infinity focus
• Compatibility: supports lenses with mechanical aperture control

How to use

Attach the Nikon lens to the adapter by aligning the lens index marks and rotating until it locks into place. Then mount the adapter with the attached lens onto the Canon EF/EF-S camera body and secure it by turning until the adapter clicks. Focus and set aperture directly on the lens; camera meters and focus confirmation (if available on the camera) can assist focusing though there is no electronic communication between lens and body. When removing, press the camera body release and rotate the adapter to detach.

Usage recommendations

Use the adapter with lenses that have a mechanical aperture mechanism for full manual control. Check lens rear element clearance and use careful handling when mounting to avoid contact with the camera sensor or mirror. For autofocus Nikon AF lenses, expect limited or no autofocus performance depending on lens type and camera body; verify focus manually when necessary.
