Don't the first party brand lenses almost always cost more than the Sigma equivalent? I expect the Pentax 50mm and 85mm to cost more than the Sigma or Tamron equivalents, but less than the Nikon flagship lenses of that FoV+aperture.
Originally posted by G.E.Zekai Currently, Canikon has no real modern pro 50mm lens (except for super expensive Nikkor 58 f/1.4G). Current models are either too soft and/or slow to focus with bad results on high MP cameras. I really wish we could just get Sigma Arts in K mount or even rebranded ones but DFA* lenses will most likely be fresh designs. Although Pentax has a good history with compact primes they haven't really build a great "Fast, Sharp, PRO" prime for some time.
I'm not sure this is true. Yes, the massive Ziess Otus and Sigma Art lenses are sharper than pretty much anything else available. But many other lenses can still reach the 36MP sensors quite well.
And Pentax has had the DFA 50mm f2.8 (really sharp, highly corrected optics) and the FA 50mm f1.4 and the DA* 55mm f1.4 (Silent focusing, WR, QS, very sharp), FA 43mm ltd (known for pixie dust, nice character, and more than decent sharpness) available for a long time now. And the super-affordable 50mm f1.8. Sometimes Pentaxians are like the stereotypical women standing in front of a closet full of clothes and saying "waah, I don't have
anything to wear!"
