No more painful focus guessing ,when you hear beep ,that is ok , say good bye to correct focus by your naked eye.

we Guaranteed for Compatibility:Tested on ALL Digital EOS Cameras (including newest 400D) ever sold and most Film EOS cameras on the market (including EOS 3, EOS 5, EOS 300, EOS 50(E), EOS 100, EOS 500, EOS 30/33, EOS 1N(RS), EOS 1V, EOS RT, EOS 630, etc). thanks !

as we all know Pentax PK F-mount lenses have their sharpness and fidelity , but Unfortunately because of absence of electronics to communicate with the camera body , we can not get Focus Confirmation and various Light Metering Modes with ordinary Pentax PK lens to Canon EOS adapters

With ordinary Pentax PK adapters some Canon EOS cameras only work as center-weighted light metering regardless of whichever setting you choose. They also lack the Focus Confirmation function on all Canon EF auto-focus lenses which provides a viewfinder indicator and optional beep sound when you rotate the lens' focussing ring up to the correct focus.

Attention :
EOS 1D ;EOS 5D ;EOS full-frame body please bid High Quality Adapter,
This adapter not fit with your camera.

Can use direct EOS camera: 10D 20D 30D 300D 350D 400D 30 or New EOS.
