The chrome Pro Adapter for M42 Lens to Canon EOS Camera with Focus Confirmation Chip, V.2 with Flange from FotodioX attaches M42 screw-mount lenses to select Canon EOS cameras. Automatic aperture and autofocus are not supported via this adapter and "stop-down" metering in manual or aperture-priority modes must be utilized, however the focus confirm chip will inform the user when a subject is in focus. The adapter provides a flange to control the iris on select M42 lenses. This version of this adapter is considered the "pro" model because its chromed brass construction is durable and made to withstand repeated use.
Compatibility
The adapter provides at least limited compatibility with all Canon EOS cameras excluding the EOS 5D Mark III for which the confirmation chip is not supported.
