I own two of these lenses and several other types of Pentax lenses. They are well above the general competition in cost and quality. Pentax for many years has and still is producing various types of high quality glass for binoculars, telescopes and photography.

This is a great lens if you need a macro. On the Pentax *1st DS it gives images that are 1.5 times the actual size of the object. The first lens arrived damaged, but it was replaced by the vendor without any hassle.

Using this lens with the K10D Pentax digital camera is a true pleasure. The sharpness of the images is outstanding!
