Originally posted by Chris Mak To be fair, when comparing to other brands, you should take their latest designs, eg. the Canon RF85mm f1.2:
quote DPReview: "As we've seen throughout all of our samples, longitudinal chromatic aberration, which typically shows up as purple and green fringing in front of, and behind, the focal plane is simply not an issue at all with the RF 85L"
I'm all for fairness.
However, the Pentax will be compared with the lenses mentioned by beholder3 - as those are cheaper (use the lowest street prices) and lighter.
And, speaking of the f/1.2 monsters, aren't we better off with Pentax going for a more reasonable f/1.4?
