I read some reviews about how bad this lens is but I decided to give it a shot anyway. I think I lucked out and got a good copy because I am very pleased with this lens. The only issue is the auto focus hunting a little. I would not discourage anyone from buying the lens on that issue though.

Sharp; great walk around lens

AF

I would give this item a better review if it was actually the item pictured and in the discription. It was a DAL lens (lesser quality w/o the quick shift focus) and not a DA lens. It would of been one thing if it was actually that was actually the item in the description (see attached photo).

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

I had just gotten the Pentax k20d body w. the 16-50 f2.8 zoom and was waiting for the WR version of the 50-200 lens. J & R had it first, and i had it the next day. The lens is nicely compact and lightweight. And i don't have to worry about the weather.

Consistent Output; Durable; Easily Interchangeable; Lightweight; Rugged; Sharp Focus; Strong Construction

Would be nice to have a little spacer between the focusing ring and the zoom ring, otherwise its a great lens that takes great pictures.

really good pircahse for my camera. has improved my shooting at sports events immensely. I have not had problems with teh speed of the zoom as shots have been focussed superbly on the subject

I always like it when I buy something that does what it says it will do. This lens does just that I own a Samsung GX20 and it works perfectly on this camera.

Got some great landscape, wildlife and people pictures at the beach. Good color, sharp rendition. Bought this along with the K7 kit that included the 18-55 mm. By adding this to the kit I have a good range for all types of landscape and wildlife photos.

First I'd like to talk about why I bought the lens. The dynamics of this lens is very appealing. To have a lens with full zoom capabilities throughout the range and close focus in a lens this size is uncommon at the very least.

As a beach comber, marsh stomper and kayaker I needed a weather resistant lens covering as much range as possible. Not only is 50mm just not wide enough for all outdoor work but my copy was not sharp enough in tele mode to make me happy so I returned it a
