It's funny, but I remember reading lots of complaints that the big photo mags only give good reviews to those companies which advertise in them (and since Pentax didn't, this was used by apologists to explain why Canon and Nikon got all the press)... can anyone tell me whether Pentax is now advertising (heavily) in Pop Photo? It might explain the rating...
Originally posted by kunik What an absolute damn shame there has to be so much cynicism regarding such an excellent lens. Optically this lens is easily better than my 24-105L Canon lens which really highlights the long term strength of Pentax which has been optics.
Personally I have had this lens for 2 years now with no problems and it is one of the reasons I have not switched fully to Canon. In fact if I could mount this plus my 50-135 and my 43Ltd there would be no reason for me to stay with Pentax.
So I'm glad this lens is getting good reviews. Now if the bad press can just be resolved all will be good.
I don't discount your experience kunik, but your comment vs. my experience might point to sample variation amongst lenses. My DA* 16-50 seemed to be a "good copy", at least based on samples I took and posted back when I got it (including 100% samples etc...), but subjectively, my 24-105L blows it away in the sharpness dept. on my 5DII Perhaps not center sharpness at f/4 (I never ran any side by side tests), but across the frame, I notice much better sharpness. It may be that I had an average copy of the DA* and an excellent copy of the L, or maybe I'm just seeing differences in the sensor/AA filter.
As to distortion, I hadn't really noticed, so I just went back through my shots with this lens and because of a combination of my shooting style and the settings I'm usually shooting in (outdoors, or indoors with shallow dof) there are only a few shots where I can see the distortion, and even then it doesn't bother me (I have a strange tolerance for distortion
). I can see how if you're often shooting in man made settings, the distortion might be much more of an issue (however I was able to fix it to a great extent with the distortion correction in DPP with the one shot I tried).
