Revuenon 55mm F1.2 MC Ricoh K mount

was looking at this lens, hoping it is a k mount.
the question is... If I modify it for the K10, will it be fully functional (including focus to infinity)

I have the Revuenon 55mm f1.2 in K mount. It works great no need for modifications. It will meter wide open at 1.2 in Av mode, or you can use the aperture ring + M Mode and the Green Button for other apertures. There are no issues focusing to infinity

And the lens is fantastic

It should be K mount, the earlier versions of the lens were M42. All are the same Tomioka design

These ones are usually labeled p/k-r or p/ka-r and the ones I have owned had this engraved onto the mount itself and those ones should fit. You will need to be cautious of the ricoh pin which may get the lens stuck on your camera and these lenses sometimes have aperture lever arm gaurd that is way to long and will prevent the lens from turning to the lock position when you put it into the camera mount. You can take the aperture lever arm off or trim it to fit. There are several threads about both these things if you need to look them up.
