Excerpt: I have a DA 15, DA 35, DA 70, M50 1.7, Tamron 70-200, and DA 16-45 in my bag. This lens is easily the sharpest. So sharp, it will cut your eyes when you look at shots from it. Aberrations and bokeh are excellent too. It also performs very well as a standard walk around lens in well lit conditions. Build quality is top notch as with all the DA Limiteds. I really like the built in hood too.
Pros: IQ, Small Size, Versatile
Cons: Short FL for macro, poor AF due to no focus stop
Excerpt: This is my first DA prime lens, and I can't speak enough of this lens in the last month or so I have purchased this. First of all, I can get closer to subjects for a more dramatic composition. Second, the colors, contrast and sharpness of this lens are extremely wonderful - to a point of this lens becoming one of my favorite all-round lenses. I am really glad I made the purchase.
Pros: Sharpness, contrast and vivid colors. Very versatile and great walkaround
Excerpt: By far my most versatile prime lens. Works as a macro, 1:1 though the MWD is indeed an issue at times. The lens is not the best "bug hunter". Wonderful product shooting lens. I like it as a general walk-around prime. I have all of the Three Amigos and find I use my 35ltd more than any of those.
Pros: task flexibility, contrast & color rendering, full time manual focus
Cons: typical sense of slower AF if not somewhat prefocused but all true 1:1 macros have this issue.
Excerpt: I am not writing a broad appraisal here. There are many aspects of this lens I have not encountered. However, in the context of a normal lens, I was quite taken with the portrait quality it showed. I'm not speaking of soft gentle creaminess and bokey, rather stunning realism. Pictures of faces are like looking into a mirror they are so clear. Because the K5 has no film grain, the effect is 3D. I think it's qualities are most clearly shown in the digital domain.
Excerpt: Bought this lens for macro and walk-around purpose. It is sharp at wide open, however it does not improve significantly its IQ as stops down. It is very convenient due to its size and sharpness. Compared its IQ to Sigma 17-50mm HSM at 35mm, it gives better IQ at f/2.8. But it is so shame to Pentax prime, Sigma zoom becomes a winner in term of sharpness at f/4.0, 5.6, and 8.0. This is the reason I gave its value to 7/10 only.
