I love this small Pentax Lens. Great for everyday shooting when you do not need to carry a heavy Zoom.

Summary: I use this Lens on my Pentax K5 IIs, I use it as my prime lens for most of the time. It is small flat and light weight. Makes carrying around a DSLR almost like a Point and Shoot Camera. Pentax Lens are for the most part over priced, but this lens is a good buy. The other 40 MM version of the Pentax lens is about double in price, this is good glass and it is a great lens for street photograph, as it is small so people do not pay much attention to you as when you are...
Summary: Super compact, super crisp. I LOVE this lens. It is so portable that I can fit this in my holster bag with the 18-55 on the camera, and almost makes the K-5 look like a point-and-shoot. The 2.8 is crisper than expected and provides a beautiful depth of field when wide open. At 3.5 and above it is sharp as a tack. Compared to its big brother this lens packs quite a punch for the price tag.
Summary: I haven't tested it extensively yet, but with the few test photos I shot, I noticed a marked difference in the sharpness/photo quality of the pictures taken with this lens vs my kit 18-55 and 50-200mm lenses. I winced to spend the money but after reading reviews I thought it might be worth it. It's worth it.
Summary: I have a lot of good to say about this lens, so let me start by telling you whats bad to just get it out of the way. 1- Purple fringing can be strong but only in significantly high contrast situations (tree branches in the gray sky, white fence/ or white floweres with sun hitting it, etc). Also occurs worst wide open at f2.8 stops to 4 stops then is gone.
Summary: Very small and light, goes very well on my Pentax k-5. Focus speed is fantastic, and makes a very small and portable camera setup. The only problem are the rubber lens cap and it does not come with lens shade.
Summary: I bought this lens as my first prime with birthday gift cards, and I love it. I do a photo-a-day challenge and this lens is great for hikes, walks, and street photography. It is so small that my K-r looks like a large point and shoot and definitely helps me not feel so awkward when I'm out taking photos in the street. Its tiny size is great for street photography since it has a 0 intimidation factor.
Summary: I wanted a lens for street photography that would not immediately identify me as a photographer from a block away. Even my 50mm f/1.4 prime was larger than I wanted. I had been debating purchase of the Limited version Pentax initially introduced but didn't want to pay the price. This lens was 2/3 the price, made for a different market, but it works well on both my K-5 and K100D Super bodies.
