Adapter rings

All M42 screw mount lenses can be used on Pentax PK cameras by using a metal adapter ring. This can save you having to convert your camera, which can be costly. It also means you have a wide range of high quality lenses to choose from. Take your pick from any of the well known brands and use your existing Pentax PK camera body.

Having this adapter also means you can share lenses between different cameras , giving you a wider choice when it comes to your photography.

Easy to use

These adapters are nice and easy to fit to the camera body, simply put the red marks on the adapter and lens collar together and then turn until they click. Attach the ring to your lens and then the lens to the camera.

To remove, press the lens lock and remove the adapter from the lens. There is also a removal tool, which is usually included with the adapter, to make this process easier.

Although the lens will fit correctly, automatic diaphragm, auto-focusing and some other functions will not work correctly while using this adapter. It is therefore recommended that you use manual or AV modes.

It is possible to use Macro rings and other accessories with this adapter in place. There is no ROM connection on the ring so the diaphragm control of the lens is set manually.


Most of these M42 adapters are compatible with Pentax K mount bodies K-7, K-x, K-r, K-5, K-01, K-30, K-5II, K-5IIs, K-500, K-50, K-3 and K-S1.
