K&F Canon EOS EF Lenses to Fuji GFX Mount Camera Adapter

The K&F Canon EF to Fuji GFX Lens Adapter enables Canon EOS EF-mount lenses to be mounted on Fujifilm GFX medium-format cameras with durable metal construction and full manual control.

The K&F Canon EOS EF Lenses to Fuji GFX Mount Camera Adapter allows photographers to mount Canon EF-mount lenses onto Fujifilm GFX medium-format camera bodies. This adapter is ideal for users who want to take advantage of the wide variety of Canon EF lenses while enjoying the large sensor and high image quality of the GFX system.

Built with durable aluminum alloy and copper components, the adapter provides a precise, stable connection between lens and camera. As there are no electronic contacts, focusing and aperture adjustment must be done manually, and lenses with electronic-only apertures will remain at their default aperture position. Infinity focus is supported.

For large or heavy lenses—especially telephoto options—using a tripod or lens support bracket is recommended to maintain proper balance and protect the camera mount.
