Originally posted by drypenn If you don't mind doing MF, a good copy of a K50/1.2 is cheaper than a brand new *55, and it has superior OOF rendering.
Though DOF is incredibly shallow at f/1.2, but in skilled hands the images from K 50mm f/1.2 are sublime.
Pentax K5IIs - Pentax SMCP-K 50mm f/1.2 @ f/1.2 Originally posted by malinku I really love the old 55mm f1.8 Pentax made. So I would expect the new 55mm to be pretty good.
I prefer the older K55mm f/1.8 - like most film era lenses it renders things differently from more recent lens designs. One of the things I hate the most about current optics is the fact that resolution takes a higher priority than overall image rendering - look at the Fuji X system lenses, they are superb in terms of resolution and contrast but they don't render things like the Pentax DA and FA primes do.
Originally posted by RAART Why not Sigma 50mm ART 1.4 DG and then take advantage of mount exchange what Sigma offers...
The sigma lens mount swap service is only available when the lens in question is already offered in the lens mount you are asking it to be switched to. Since the sigma 50mm f/1.4 isn't natively made in K mount there is little point in asking.
