I've tried generic screw mount adapters, but none of them provide as consistent and solid of a connection as the Pentax original. I've used it many times without the cross threading issues cited with third-party adapters, and it has always been easily removed from the camera without the need for tools. Simply push in the spring/clip with your finger and it rotates out of the camera mount.

I'm glad Pentax has made this adapter available again, the off-brand adapters all seem to have problems or risks of getting a lens trapped on the camera.

The Only Adapter to Get

By

This is the only adapter to get for mounting M42 legacy lenses to your Pentax K digital camera. Anything else and you risk getting a product stuck on your camera. I've been using mine for years with no problems or issues. I'm going to get another one just to have one as a back up. Highly recomended.

Original PENTAX

Allows use of M42 lenses on Pentax DSLRs. I have a couple of "copies" but never felt comfortable using them. This is the real deal, at a great price.

Pentax OEM adapter

By

from Alabama  -  Hobbyist/Enthusiast

Works perfectly. Says "Philippines" instead of the old ones that say "Japan". But is smooth and does not get stuck on the camera.

Silvia G  Is this the right adaptor to fit Pentax M and K lenses to a Canon 5D mark II?
IAN E  No. This is for adapting later Pentax bodies to accept screw mount lenses. So, for example, if you have lenses for a Spotmatic that you want to use with an MX body, you can put this adapter on the MX, and screw the lenses onto the MX body. Look for a K mount to EOS adapter.
