Originally posted by slackercruster Pentax makes good quality, mid level gear that can produce decent photos. The Pentax glass generally comes in about 55-60% as sharp as Nikons or Canons best pro level glass on the optical bench tests.
There was a lot of common sense in your post (which won't appeal to pixel peepers) above - however the statement quoted could not be more wrong - 55-60 % !?! I think you need to go and check out those test results again ! Pentax's best glass (FA Ltd, DA* and DA Ltd) is more often than not on the same level or thereabouts with Nikon's/Canon's and in some cases even blows away the best comparable Nikon and Canon's L glass, as tests have proven. It is a fallacy to say that the best Nikon / Canon glass is better, almost just because it is so expensive and the assumption therefore is you are getting more for your money.
However that said let's also make it clear that just because a lens is sharper, has less Chroma/PF, faster AF etc. etc. doesn't always mean it produces a better photo since considerations such as rendering and bokeh, two (
almost impossible to measure) qualities, not only influence the quality and IQ of a picture more but are totally subjective !
