SMC Pentax-A 100mm f2.8 First Impressions
The Pentax-A 100mm f2.8 is manual focus macro lens. While it is not an autofocus lens, this Pentax-A lens does offer automated aperture priority metering when used on a Pentax digital SLR body such as the K100D. Anyways, for macro shooting, autofocus is not especially useful. As a general purpose lens the 100mm macro is very versatile, if a bit long on digital. On a film body it is nearly perfect. When used as a general purpose lens the amount of turning needed to focus can make it a little slow for subjects moving around quickly. Otherwise there's little to complain about. It's sharp, out of focus rendering is smooth, and while not small, it's not an overly large lens. See below for a few samples:
