Users of Pentax film and digital cameras can use this lens, with its full image circle covering both APS-C sensirs and the 35mm frame. The lens is digitally optimised with SMC coatings to reduce flare, reflections, ultraviolet rays, thereby improving contrast.

Good sharpness; consistently low fringing; clamp feature; focus switching

Not very much

Very versatile lens, useful not just for macro, but also portraits, landscapes, etc. The sharpness and contrast is terrific even when combined with teleconverter, tube, or dioptric attachment lens. This gives so much more combinations and possibilities.

excellent image quality; small and light

The best lens I own. I never knew how many photos I was missing out on until I got a decent macro. It's also a great street lens (on full frame) and portrait lens (on APS-C or cropped).

Have wanted a Macro lens for some time. When Sigma stopped making Macro lens for Pentax cameras, I started looking at Pentax Macro. Used it the next day in the early morning in my backyard taking some Macro nature photos with the frost just starting to melt in the morning sun.

These older "prime lenses" are pretty cheap used and work fine on new Pentax DSLR cameras. They offer the professional look of a shallow depth of field, attractive bokeh, and the clarity that a simpler lens offers over the zoom stuff. In addition to that - it captures more light thanks to a f2.0.

I've only had the lens a couple of months. So far, I've used the lens for Christmas portraits, some low light shots, and landscape shots. It is fast and easy to use. My only gripe is the AF hunt if I forget to engage the clamp.

This lightweight 50mm macro lens has a bright maximum aperture of f/2.8, costs around ￡320 and offers life-sized magnification at its closest focus distance. On a Pentax DSLR this lens provides an angle of view roughly equivalent to a 75mm lens used on a 35mm camera.
