great price, excellent lens


from Oregon  -  Photo Enthusiast

The Pentax Limited lenses have a well-earned reputation. I owned this before but sold when finances were tight. This barely-used lens was priced low so I'm happy to own it again. Thanks Adorama for dealing in used gear and pricing it well!


Wonderful image quality, fast focus.


from Oregon  -  Pro Photographer

This lens pretty much stays on my K5. Great for street photography very unobtrusive. I use both Canon and Pentax for my pro work and the image quality of this lens rivals my "L" lenses which cost thousands more. It is a wonderful lens I take with me everywhere.


Perfect Lens


from Malaysia  -  Casual Photographer

A very perfect lens.

Such a beautiful lens!


from Messimy, France  -  Photo Enthusiast

Since I received this lens, I see that my pictures have a sharper, true colors, beautiful bokeh. The very fast autofocus and aperture to 2.8 contribute to a real pleasure in low light photography. This lens takes place on my Pentax for a long time.

Great lens!


from Adelaide South Australia  -  Photo Enthusiast

Very very high image quality, colour and contrast. Nice focal length for an APS-C sensor camera. Compact lens size doesn't put people off of having their photo taken.

One of if not "the top Pentax Prime lens


from Central New Jersey  -  Photo Enthusiast

The "tiny Tim" of Pentax DSLR lenses. Compact to a fault, bridges the gap from point and shoot to the prosumer DSLR enthusiast. Unique appearance and probably the all around, go to everyday carry Prime for the Pentax lover. Get a gaggle of these limited lens-15mm, 40mm & 70mm and don't forget the Pentax case for them-outstanding! Don't forget to read the Pentax Forum reviews on this baby.

from California  -  Casual Photographer

With this lens on my K-x, I have a very compact and lightweight camera. Yet despite it's small size, the lens feels very powerful. The AF is quick and the MF is decent and quite usable, despite the thin focus ring. This lens is a very good short portrait lens and the bokeh is very pleasant and smooth, which adds a lot of emphasis to the subject.

Light, Fast, GREAT portrait lens!


from Denver, CO  -  Semi-pro Photographer

Saturated colors, slightly cooler than typical Pentax lenses. Sharp. Small enough most people don't notice I'm there. Sharp. Oh, and did I say sharp? Wonderful bokeh.

A Must Lens for K-x


from Cincinnati, OH  -  Photo Enthusiast

This is the smallest pancake lens ever, I think. If you have a K-x, which may be the smallest DSLR, then DA40 will give you the most tiny combination for travelling. In addition, high performance in high ISO on K-x makes D40 quick enough. And bokeh is great when at f2.8. No Purple Fring.
