Konica AR to Canon EF/EF-S adapter

This adapter lets photographers mount Konica Auto-Reflex SLR lenses onto Canon EOS EF and EF-S camera bodies. It is built for shooters who want to use vintage manual-focus glass on modern digital SLRs. The all-metal brass construction provides a secure, stable connection between lens and camera. No electronic communication is added, so exposure and focus remain fully manual.

Infinity focus with manual control

The adapter is engineered to achieve infinity focus, allowing the lens to reach its full focusing range on the Canon body. Precise manual focusing gives the user complete control over depth of field for creative work. Because there are no electrical contacts, the camera cannot control aperture or record EXIF data from the lens. Automatic metering modes that rely on lens communication will not function.

Brass and metal construction

The adapter body is machined from durable brass and metal for long-lasting reliability. This rigid build prevents play between the lens mount and the camera flange, preserving optical alignment. The solid construction also protects the lens mount surfaces during repeated attachment and removal. There are no moving parts, springs or levers inside the adapter.

Questions about this item

Will this brass adapter let me reach infinity focus with my Konica AR lenses on a Canon 5D?

Yes, the adapter is built to deliver infinity focus when mounting Konica Auto-Reflex lenses on Canon EOS EF or EF-S bodies such as the 5D series.

How can I confirm the adapter is seated correctly after attaching it?

The lens should lock firmly with no wobble, the aperture ring moves freely, and the viewfinder shows a sharp image at the infinity mark when focused on a distant subject.

Does the package include a lens-cap or rear-cap for the adapter itself?

The adapter ships alone; you will need to supply your own Konica AR rear cap and Canon EF body cap if you want to protect the mount surfaces when the adapter is stored.
