It works as well as my Pentax 18-55 f4-5.6 WR lens. Now I have an essentially 10x capability. Remmeber to turn off the camera before swapping out lenses!

Typical kit len with WR

Pentax 50-200mm f/4-5.6 ED WR Telephoto Zoom Lens is a typical kit len for Pentax K-mount DSLR products, it includes a len hood which is great for the bright light outdoor photo shooting. In addition, it is with metal mount apart from DAL lens from Pentax which is constructed with plastic mount.

Pentax 50-200mm f/4-5.6 ED SMC DA WR review by Jon Schick

As with the 18-55WR, it's nicely put-together and feels a step up from many other kit lenses (including the older Pentax 50-200). Nice metal mount, and a thoughtfuilly-designed lens hood that allows the use of polarising filters.

Weather resistant; very compact and reasonable performer for the price

Performance a bit variable depending upon focal length and aperture
