Pentax DA 40mm f/2.8 Limited Reviews

High quality compact lens

By Adrian
Rated 5 out of 5

Ive had this lens for over two years. Its always performed great, image and build quality are excellent, I use it all the time. Its not about having a large aperture, its having a relatively fast normal lens without taking almost any space in the bag. If you like to travel light, or want a standard lens to complement wider or longer zooms, this is an excellent choice.

Nice all-rounder

Great build quality, same for iq, tiny, very usable focal length on both apsc and 35mm. What more could you ask for? Faster aperture? Yes, it is not the fastest prime out there, but it's not that slow either and a compromise worth making given the other qualities it has.

Excellent lens that requires a little getting used to

I got this lens for street photography and some portraits. So far, it's been great: it's *very* sharp, very light, and very solid. The auto-focus is also quite fast and accurate--which is a good thing, because using the manual-focus ring on a pancake lens is a little difficult to get used to. The focus ring is so slim that it's 1. hard to find with your hand when you're already looking through the lens and 2. a little difficult to manipulate because it is so thin. Also, while the metal, screw-top lens cap and hood do feel very solid and well-made, the cap itself is tiny enough to lose easily, and also requires a minute to remove--so if you're trying to capture the decisive moment, you *really* need to keep that lens cap off, more so than with normal lenses.So far I'm really liking the lens, and the only reason I rate it 4 rather than 5 stars is that I have already found I wish it were an f/1.4 (have missed a couple of light/DOF opportunities). But that's not really the lens's fault.

Good quality image

Paired it with my new K-5IIs, image quality is very close to a full frame format.

Incredible optical performance and character. For portraits, amazing under existing light or in the studio; here are two examples:

The focal length is very usable, even though it gives a very slightly narrower angle than a 35mm, but I can't say I actually notice that. Mechanically it works and feels great, and image quality is nice too. Highly recommended if you want a compact setup.

question

will it work as a full frame on the new Pentax k1?
Asked by: Anonymous
The Pentax HD Pentax DA 40mm f/2.8 Limited Lens is designed for use on APS-C sensor cameras; however, many owners and users of the lens have often stated that they happily use this lens on their Pentax 35mm film cameras and the lens does cover the full image frame. As such, the lens should also work for use on the full-frame Pentax K-1 DSLR camera. (Do note this claim has only been made about the Pentax HD Pentax DA 40mm f/2.8 Limited Lens, and does not apply to other Pentax DA Limited lenses).

question

What are the differences between this HD lens and the less expensive version?Is it just coatings, is it an entirely different design, is it a different type of construction? It is a shame that it doesn't have the WR feature.
Asked by: Anonymous
The one you are referring to has has better coatings and is an updated version. With those coatings it will perform better and in most cases give you a sharper images.
