Excerpt: One thing that has never been mentioned (or I have not seen written) is that the images rendered by this lens is obviously "digital", for lack of a better adjective. Nothing wrong with being "digital" but it lacks the FA Limited's charm. Still, it's a lens worth having.
Excerpt: Brilliant gem from Pentax. Small, high quality, great build and overall great image quality. It is well larger than the 40 or 21 Limited, more in the order of size of the 40 limited. However, for a 15mm, that is really small. Compared for instance to the 10-20 Sigma (3.5) it is amazingly small.
Excerpt: I needed a wide angle lens for my trip across the country and this was the one I got. I stuck with a prime because I was desiring image quality over zoom flexibility. And choosing this over the 12-24 was good since I got image quality at a less expensive rate.
Pros: wide, beautiful build, great color and contrast, crisp & sharp
Excerpt: The issue I have is that in some condition the field curvature mean you'll get soft border even at f/9-f/11. The lense is sharp on the center. it can be sharp on the corners on the rights photos but overall on many shoot it will be soft on the corners no mater what.
Pros: Fantastic contrast and flare resistance, small, light
Excerpt: I wasn't sure that I needed this lens as I already own the DA12-24 however once I put it on the camera I realized how much different it handled than the 12-24. It is small, light and easy to carry. I have taken some of my best images with this lens.
Excerpt: My first APS-C lens, wide lens and DA *limited. Bought for landscape in low light (since I have Tamron 17-50mm/F2.8 that is very good at F5.6 and smaller). I was striked by the color and flare resistant it has, but little bit surprised by distortion. May be, I'm not used to such wide lens.
Pros: all metal, flare resistant, beautifull color
