One of the challenges of using manual focus lenses on Canon EOS bodies is the lack of focus confirmation. With AF lenses, all Canon EOS bodies confirm focus with a green dot in the viewfinder and an optional audible beep. However, when non-EF compatible lenses are used via an adapter, this focus confirmation is disabled. The Generation v10 Focus Confirmation Chip solves this issue by 'tricking' the Canon EOS body into thinking an EF lens is attached, enabling focus confirmation indicators to work with any lens.

The adapter's high-tolerance precision craftsmanship ensures a secure connection between your camera and lens. The leaf spring design holds the lens tightly to the adapter, mirroring the leaf springs in the camera body to eliminate any play. The all-metal design and polished surface are engineered to provide a smooth mounting experience for years to come. The adapter's depth is designed to account for the differences in focal flange distances between the lens and camera, ensuring all lenses will focus at least to infinity.

Please note, this is a manual adapter, so lens functions that rely on electronic communication with the camera body (autofocus, AE metering, image stabilization, etc.) will be disrupted. Set your exposure manually or meter using your camera's Aperture Priority (stop-down) mode. If your lens does not have a manual aperture control ring, the lens aperture will revert to its default position.
