Released in 2005, the Pentax 50-200mm ƒ/4-5.6 ED SMC P-DA represents the consumer end of Pentax's telephoto zoom lens offerings.
The lens is designed to fit the digital APS-C sensor, but I didn't find any evidence of corner vignetting on a film body until 135mm or longer. It's also a variable aperture lens, in that as you increase the focal length, both the minimum and maximum aperture sizes increase. The lens takes 52mm filters, comes standard with a circular-style lens hood, and is available now for around $200.
