Brian, Paul has already written what I wanted to say. I find it sharper than my FA 50/1.4 in the comparable range of settings. Also, It is much sharper than 17-70/4 in the range that they overlap.
I bought that lens almost 1.5 years ago. Before that D-FA 100/2.8 macro was always in my bag. Now, 50-135 replaced it for all the occasions, except when I shoot macro. I never tried 77/1.8 or 70/2.4 so I cannot compare it to those. I think I mentioned this photo before: http://www.pentaxphotogallery.com/home#/section=ARTIST&subSection=198943&subSubSection=11182395&language=EN It was taken with 50-135 & 1.7x Pentax AF converter. (I was going to show Rob's photo of me taking that photo, but he removed his photo gallery :-( ). So, my claim is that 50-135 is on par with good primes.
