traveling photo gear

A great compact light weight lens for everyday use. This lens focuses quickly and quietly. The only drawback is the fixed focal length at 40 mm; after using my camera with a 17 - 70 mm zoom for years it seems limiting in what pictures can be taken. A good lens for everyday shots but for varying subject distances it can seem restrictive.

great price, excellent lens

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.

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.

Such a beautiful lens!

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!

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

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.

Excellent

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!

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

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.

a must have lens

This lens is super sharp. It has excellent contrast and very saturated colors. There were few complaints from other users about the lens cap but it did not bother me too much. The ability to be able to carry the lens in your shirt pocket more than make up for the it. When shooting super high contrast image at 2.8 there is slight loss of detail (low contrast)in the shadow. But under normal shooting, it should not show. This lens is as good or better than other manufacturer for far less of your hard earned money.

Pentax SMCP-DA pancake lens

I got this lens due to feedbacks, and it's size. I have found it to be a very nice lens, and it really cuts down on the size of the camera. Sharpness and color meet my needs. I did not subject this to any real deep testing. I looked at my results and am pleased with it's performance. It's speed is helpful in low light conditions. It is a set lens at 40mm which is roughly the equivelant of a 60mm in 35 film. For general photography I am happy with it. The cap is very small and screws on which secures it well, but could be easily lost if you're careless at all. All in all it's a nice space saving lens and may well become one of those "remember the old "pancake lens" Pentax used to make, wish I had one". Well, I do. Dan

Smallest DSLR/Lens combo on the planet!

I use this on my back up camera; Pentax DL-2 (same as the DL-1). The combo is the worlds smallest DSRL/lens combo. The lens is a mini work of art. I use it for travel and when in the car (mostly). When people see the camera they are not aware (sometimes) that the lens is on it... The fact that it is a high quality and very well made lens makes this a MUST have.

Excellent lens for 35mm, too

I use this lens exclusively with my 35mm film bodies, an *ist and a ZX-L. The lens works perfectly on both of them, and makes for a very compact outfit, perfect for carrying around. The DA 40mm is a sharp, excellent lens.
