The best part is that the current Pentax KA mount is a variation of the original K mount that was introduced in 1975. There are more than 40 years’ worth of K-mount lenses and the majority of these lenses can still be mounted on the Pentax K70, although some will limit the use of some camera features.

The Takumar branded lenses were well respected for their line of Super Takumar, which designated the high performance coating applied to the lens as well as the optical formulas used to make them. The majority of the industry at the time was still satisfied with the variations of the "plumb" coating process and later some of the two and three layer processes as well. Asahi Pentax soon introduced the Takumar Super-Multi-Coated line of lenses which was a 7 layer process as the industry had just caught up with similar forms of 5 layer multi-coated optics. Eventually Asahi Optical and Pentax slowly shifted much of their lens production under the Pentax name and transitioned some of the successful designs that were first introduced under the Takumar name to use Asahi/Pentax badging as well as beginning to use the "smc" abbreviation.

Stopped down, it provides excellent results for sharpness, but many people will be buying it for its ability to shoot at ƒ/1.8, where it offers only mediocre performance. If you need to shoot at wide apertures, you are better served with Pentax's more expensive options; if you are looking for a portrait lens that you'll stop down to at least ƒ/2.8, then this could be a good alternative for you.
