Well you have stated this three times now. Talk is cheap. I would like to see a comparison of the same image between both lenses showing that the 55-300 is indeed sharper with "much better color and more contrast." People make these kind of statements about lenses all the time, but I rarely see them back it up. Some of the statements remind me of the things people say when tasting wine. "It lacks limpidity and brightness."
I'll bet it would be very hard to see the difference between those lenses. I already demonstrated that it is hard to see the difference between the DA* 50-135 and the 18-250 unless you go to 100% crop, and even then it is difficult.
Originally posted by Alfisti There is WAY more to it than Lw/ph, the 18-250 has no localised contrast. I have simply never, ever seen images like this from the 18-250
Here are 50 good ones from the PPG.
PENTAX Photo Gallery I don't find the 26 pics from the 55-300 any better overall. Certainly no noticeable sharpness difference. The point is that it is silly to argue about lens sharpness when the difference is almost imperceptible. "No localised contrast" is a red herring. Contrast and color are as subject to personal preference as is bokeh. The OP's original goal was
sharpness.
