Summary: Photographers who have been around for a while and know a bit of history, know that Pentax has often delivered good quality equipment. Pentax users are a resilient bunch ever unbending to the likes of Canon and Nikon. And yes, they do have a reason for that. Pentax may not spend a lot on marketing (hence such little brand awareness amongst the younger generations), but heck I guess they're too busy spending every penny they've got actually making great products instead...
Summary: I am a Canon shooter (I shoot a 5DM3) and this 15mm Limited prime is the main reason why I am still hanging on to my Pentax cameras. Great piece of glass. When paired with my Pentax K5, it is my ultimate landscape setup. Unbelievably sharp at F8.
Summary: Although I have only used the lens once for a walkabout in town to test it, it appears to be a quality lens as already commented on...just a bit of information if anyone plans to use a protective filter...which I prefer to do...due to the fixed lens hood the first filter I tried did not work...I now have a Hoya NXT HMC UV filter mounted...which does not impede the lens hood and is threaded on the outside so the supplied lens cover will screw onto it...
Summary: This is the most underrated Pentax lens, but it is a real gem. Pros: -Close focusing (less than the specified 17cm). -Large aperture. Shallower DoF if you need it. Best results @f/5.6. -Filter thread. -Autofocus with full time manual override. -IF (Internal focusing). Cons: -Weight (solid metal construction, metal filter threads). -77mm filters, no stacking due to vignetting, huge lens hood (takes up to much space, so I left it in the original box and stowed it away).
Great lens, but wish the images were a little more sharp.

Summary: This is a fantastic lens, however as others have stated photos are not as sharp as they shod be at lower f-stops. At f2.8, unless you are focused to infinity, the in-focus image is not tack sharp even with a tripod. The lens does create a nice bokeh however, and for landscape shots it is nice to have a fast prime lens to handle low-light conditions. Lens performs best with an aperture starting at f4.0 for shots that have closer subjects.
Summary: Highly recommended lens. I wanted a fast, wide angle lens to complement the rest of my collection, and this one fits the bill. I take a lot of pictures for official ceremonies indoors, so this matches up well with my portrait lens.
