Designed for exclusive use with Pentax KAF-mount digital SLR cameras including the *ist D and the *ist DS digital SLRs, the Pentax DA 50-200mm f4-5.6 ED lens offers 4x zoom coverage in the telephoto range. Further, the lens features an angle of view from 31.5 degrees to 8.1 degrees (equivalent in focal length from 76.5mm to 306mm in the 35mm format).

The lens also incorporates an Extra-low Dispersion (ED) glass lens element (11-element/10-group optical construction) and two aspherical lens elements for true-to-life image reproduction and overall size reduction. The image circle in DA-series lenses is designed to perfectly match the 23.5mm x 15.7mm size of the CCD used in Pentax digital SLRs to optimize camera performance. The new design also contributes to a drastic reduction in size, weight and production cost, compared to 35mm-format counterparts with similar specifications.

Other features include:

• Compact dimensions with minimal aberrations
• Responsive Quick-Shift Focus System allows instant shift from AF to MF
• Comes with a lens hood to minimize flare and ghost images
• 52mm filter size

 "Pentax 50-200mm lens" 2010-03-15
By Wayne E. Swanson
This is a very sharp lens. My contest photos have scored very well since purchasing this lens.


 "Nice little mid-range lens!" 2010-03-07
By BBooDad (Baraboo, WI)
I originally bought this lens with my Pentax K10D a few years ago, and used it some then, until I got a Sigma 28-300, which I used virtually always, with just occasional swapping with the 18-55 kit lens. Unfortunately, my Sigma fogged up recently going in and out of a cold hockey rink to the warm concessions area, I think. And it never fogged. (I suppose I could sell it on E-bay... which is why I never buy that way!)

Well out of the closet came the 50-200 for today's game. I was very pleasantly impressed with how well it worked for taking pictures out to the ends of the hockey rink, although I was above mid-rink doing the scoreboard. The pics were brighter and sharper than the Sigma's ever were. While it certainly isn't perfect (I'd love a F2.8 or similar expensive monster!) it does a great job for the price. So 5 stars.

In fact I like it so much that my next long glass will be the Pentax, too. Sigma and Tamron have Pentax beat for inexpensive all-in-one, but the Pentax sharpness is worth the lens change.


 "Another Great Lens from Pentax" 2010-01-30
By A. Stackhouse
I bought this lens for my fiance for Christmas (and of course I had to test it out first once he opened it) and I love this lens. For the mm range it's very compact and easy to lug around with the camera. It's quality built and has the standard 52mm size (which is great since his old filters are 52mm). Takes great pictures both indoor and out (although you aren't going to get the good wide angle shots you would with less mm). Would recommend this as a great starter telephoto. You can't beat the price/quality of this lens.

By Gisela H. Rosengren
Was hesitant to buy from a new vendor with no reviews. My worries were unfounded. The lens works great and I have used it over the Holidays with excellent results.
The lens was shipped much earlier than listed . which was a wonderful surprise. THIS ITEM WAS PURCHASED THRU AMAZON.


 "Great lens...small profile" 2009-10-30
By Jeffrey A. Field
I own a Pentax K10D that came with the 18-55 mm lens. I was looking for a lens that would allow better zoom. So far it has lived up to my expectations. The compact size is a plus. The profile is nearly identical to the 18-55 mm. Having a small Pentax camera bag, I can manage to fit the camera, two lenses, and all the accessories in to a grab and shoot bag. The lens work fast, feels well constructed and images have been fantastic. Excellent price too.
