K&F Concept K/AR-EOS R – Konica AR Lens to Canon RF Mount Adapter

The K&F Concept K/AR-EOS R adapter lets you mount Konica AR-mount lenses on Canon RF-mount (EOS R) cameras. It has no electronic contacts: you focus manually, set the aperture on the lens, and the lens focuses all the way to infinity. The metal body holds the lens firmly, and a red dot makes mounting and removal easy.

Konica AR lenses on Canon EOS R cameras

With the K/AR-EOS R adapter you can attach Konica AR-mount lenses to Canon RF-mount (EOS R) cameras and keep using them on a modern body. The adapter is precision-made, so the lens sits firmly and focuses all the way to infinity.

Solid metal construction

The metal adapter is durable and fits the lens and camera precisely, so the lens is held without play. A red dot makes mounting and removal easy.

Manual focus and aperture

You focus with the ring on the lens while the camera works in aperture priority or manual mode. The aperture is set with the aperture ring on the lens.

Camera settings

Before first use, enable the option in the camera menu that allows the shutter to be released without a lens attached (Release w/o Lens). The camera does not recognise an adapter without contacts and would not release the shutter without this setting.

Compatible cameras

The adapter is designed for Canon RF-mount (EOS R) cameras, for example Canon EOS R, RP, R5, R6.

Before you order

You will find the mount type of your lens and camera in their manuals or in the technical specifications on the manufacturer's website. The K/AR-EOS R adapter is designed for a Konica Auto-Reflex (AR) lens on a Canon RF (EOS R) camera.
