comment:I really like this lens as my "walkaround" lens. My copy is pretty consistent in its sharpness at f/5.6 and up throughout the range. I like the compromise the designers took to optimize sharpness at the expense of distortion and compactness at the expense of some vignetting. The distortion and vignetting are easily corrected in PP. Is it as sharp as my Tamron SP 90 Macro or KM 28-75 (stopped down)? No, but the pics do sharpen up nicely in PP. For its intended purpose I find it hits the sweet spot compared to the 18-200's. Build is nice and solid for its weight, "tighter" than my KM 28-75. I like the black "satin" finish.
