1. Introduction
This manual provides instructions for the proper use and care of your Fotodiox Lens Mount Adapter. This adapter allows you to mount Nikon Nikkor F Mount D/SLR lenses onto Canon EOS (EF, EF-S) Mount SLR camera bodies, expanding your lens compatibility options.
The adapter is designed with high-tolerance precision craftsmanship, ensuring infinity focus or beyond. It features an all-metal design with hardened anodized aluminum construction for durability and lasting quality.
Important Note:

5. Operating Instructions
Since this is a manual adapter, electronic communication between the lens and camera is not supported. You will need to operate your camera and lens in manual modes.
5.1. Setting Exposure
- Manual Exposure Mode: Set your camera to Manual (M) mode. Adjust the shutter speed and ISO on your camera, and the aperture on your lens (if it has an aperture ring) to achieve the desired exposure.
- Aperture Priority Mode: Set your camera to Aperture Priority (Av or A) mode. You can set the aperture on your lens (if applicable), and the camera will automatically select the appropriate shutter speed.
- Lenses without Aperture Ring: If your Nikon F lens does not have a manual aperture control ring (e.g., some G-type lenses), it will operate at its smallest f/stop by default when mounted with this adapter.
5.2. Focusing
Focusing must be done manually by rotating the focus ring on your lens. Utilize your camera's focus aids, such as Live View magnification or focus peaking, for precise focusing.
5.3. Camera Settings for Lens Adapters
Some camera models require a specific setting to allow shooting without a native lens attached. Refer to your camera's manual to enable 'Shoot Without Lens' or a similar function.
