PK-EOS Adapter Ring for Pentax K Lenses

This PK-EOS mount adapter lets photographers attach manual Pentax K, Phoenix, Ricoh or Vivitar lenses to Canon EOS DSLR bodies. The metal ring has no electronic contacts, so aperture must be set on the lens itself. It provides a solid, high-precision fit with a smooth copper interface that protects both lens and camera mount during use.

Check lens compatibility and manual aperture control

Before ordering, verify that the lenses you intend to use are manual Pentax K mount types, because autofocus or electronic PK variants will not communicate with the adapter. Ensure your Canon EOS body can operate with stop-down metering or manual exposure mode, since the ring transmits no aperture data to the camera. The adapter measures approximately 2.76 by 2.76 by .39 inches and adds minimal bulk to the setup.

Suited for legacy manual-glass shooters on Canon

This adapter suits photographers who already own manual Pentax K mount lenses and want to use them on Canon EOS DSLR cameras without electronic coupling. It is not for users who require autofocus, EXIF data transfer or automatic diaphragm control, nor for owners of purely electronic PK lenses that lack an aperture ring. Buyers needing a retail package should also look elsewhere, as the item ships without one.
