There IS an SMC K mount 135mm f2.5 that is a good and sought after lens, but is it does NOT say "Takumar" on it. It simply says SMC Pentax. If you find that, buy it. It is purportedly the same optical design as its predecessor, the screw mount 135mm f2.5.
One thing I have learned is that faster does not necessarily equal "better" for Image Quality. Often the opposite is true. (I LOVE the old preset screw mount Tele-Takumar 200mm f5.6 for example, for it's color rendition and contrast, even though it is not as fast as the more common f4 200mm lenses).
