audiobomber: DPR needs to change their dynamic range measurements. The current system favours manufacturers who apply heavy tone curves to boost jpeg DR. You can't compare DPR measurements fairly between say an Olympus EM-1 or Canon 70D vs. a Nikon D7100 or Pentax K-5 II, because the first two manipulate the tone curve, and DPR measurements hide the manipulation.
DXOMark results are the only accurate measure of dynamic range, and DPR staff know it. What they are showing as DR on this site is deceiptful. At least report on both, especially since DXO is now affiliated, and proper (accurate) raw results are readily available.
I agree, and was surprised looking at DPR's charts showing the D7100 having wider Dynamic Range than my D600. Also seems to favor this 70D in the highlights. No way that's correct. I'll believe DxO's charts first. DPR's is oddly skewed, and by judging from many of the comments here, readers know it...
Why on earth would anyone pay almost $1300 more than the 50 1.4 for this lens? Seriously.
