Customer Reviews

Legendary Lens in the Making
This lens is built to last a lifetime. Auto-focus is very fast, accurate and nearly silent on my K10D. Sharpness is excellent wide-open at f4 and continues through at least f16 before diffraction begins to take a toll. The tripod mount is very well made and allows the photographer to flip the camera from landscape to portrait position with great ease. Color rendition is superb and the bokeh is like the finest creamery butter. I've already used it in mild rainy conditions with no adverse effects, thanks to its weather-sealing. Vignetting and chromatic aberrations are very well-controlled. I predict this lens will achieve legendary status in the years to come.

Top of The Line
Auto-focus is very fast, accurate and practically silent on my K10D and K20D. Excellent Sharpness. Colors are great on either camera but superb when used on the K20D in Landscape Mode. Bokeh is smooth and creamery. Great on a tripod or hand held. I have used this lens to capture eagles in flight at Real Foot Lake in Kentucky, Bears in the Great Smokey Mountains, and as a macro in the Rose Garden of Cape Girardeau all with fantastic results. Cropping to zero in on my Bears left little or no distortion and maintained the creamy bokeh. I have not noticed any Vignetting and chromatic aberrations yet. I highly recommend this lens to all Pentax users. This has to be the best lens Pentax has made and I own six Pentax lens so far.

Lens Review
I gave this item as a gift to an expert photographer, who indicated that this lens has been the most desirable addition to his collection of other PENTAX lenses.
