Excerpt: It is not the perfect lens, mainly because it is quite soft on borders, even stopped down. My understanding is that this is not softness but field curvature. The result is the same: border tend to lack sharpness even stopped down... At least when you put focus to infinite.
Pros: great colors, small, light, perfect walkaround lens
Summary: This compact gem is perhaps the perfect little walk-around lens for your Pentax. Unobtrusive, it gives your camera a unique perspective that doesn't scream wide angle but is wider and can be more useful than (35mm equiv.) 35 and 50mm focal lengths. Like the 43mm Limited on Pentax film 35's, it just looks right when you raise it to your eye and the resulting images bear this out.
Excerpt: One aspect that amazes me with this lens is the possibility of using it hand-held at very low shutter speeds. At 1/10 the images are still crisp at 100% viewing. I put this down to the balance/weight of the lens.
Excerpt: Quite simply an excellent lens for street photography, but also for landscapes (although there I might prefer the 15mm). The quality is up to the limited standard, and this lens is very compact and light. It's size makes it an excellent compagnon in the town or on a hike.
Pros: Color, size
Cons: working with filters and the lens hood combined
Excerpt: This is among my very favourite of the Pentax Limited lenses. It is small, light, discrete and versatile--a perfect walk around lens. It is a handsome looking lens and the lens hood does a great job of protecting the lens itself. Because it stays firmly in place the hood really eliminates the need to use a protective UV filter. The sharpness and colour rendition are spot on. Photos look great straight out of the camera.
Pros: close focus distance, sharpness, colour rendition
