Pentax K series lenses

First generation of smc Pentax bayonet mount lenses introduced together with the Pentax K2, KX and KM 35mm film SLR cameras. They go from a super-wide 15mm to a super-telephoto 1000mm, and most of them are based on the SMC Takumar lenses. All of the lens elements are Super-Multi-Coated, even those elements that are cemented together. This increases the light transmission and color fidelity of the lenses while reducing flare and glare even better than the SMC Takumar lenses.

A number of other changes and improvements were also made. All lenses have textured rubber focusing rings for a better grip. The minimum aperture of all the lenses had also been changed. The Pentax lenses no longer have a stop-down lever and when the lens is removed from the camera body it closes down to the set aperture.

With an inner diameter of 45mm, the Pentax K mount can easily handle fast lenses like the all new smc Pentax 50mm F/1.2. It is extremely quick and easy to change lenses. The auto diaphragm and full aperture metering are coupled as you twist the lens.
