Pentax HD 20-40mm 1:2,8-4 DA ED WR silber

The lens performed very well in cold weather (10-15 degrees F). I took 30 pictures of the Northern Lights in Tromso, Norway and they came out as well as I could have hoped, with 10 second exposure. The lens (with a Hoya 55mm NXT plus UV filter) did not fog and remained quite tight. The background is sharp, no flare.

Good for travel. A bit of a departure from the other Limited lenses I own, and not as successfully because of that. I like this lens but love the 15mm and 70mm.

Bought this 20-40mm lens in the silver edition to match my Silver Pentax KP.! Very solid build !! Thats normal for a Pentax Limited lens!! On a Aps-c camera this I would be a 31-61mm, little odd but still will make for a good allaround lens!!

Got it as a part of the KP kit. Feels solid in the hand, very smooth mechanically. Rendering is pleasing to the eye, some minimal distortion on the wide end but I am not interested in shooting brick walls. Minimal purple fringing, almost non existing, you have to really look for it. Flare, hard to induce. Sweet travel zoom that will spend most of its time on the KP.

I was looking for a 'standard' lens for my lovely neat white K-S2 body for use as a 'walk-around' combo for travel pics. The ideal boxes I wanted to tick were; 1. Silver or white. 2. Short focal length 3. Weather resistant 4. HD coating. 5. Pentax Limited series This ;lens does the lot - in fact I think it's the only Limited zoom and the only Limited WR lens. For me it was the perfect solution and has performed very well in the field. It also gives the K-S2 a sturdier feel with a lovely positive action. Like I say, for me, perfect.
