Pentax 40mm f/2.8 overview

  • 1Description

The black HD Pentax DA 40mm f/2.8 Limited Lens from Pentax is a pancake-style prime normal-length lens providing a 35mm-equivalent focal length of 60mm. The standard 39° angle of view is well-suited to everyday situations and the slim profile is ideal for an inconspicuous shooting style. A high-grade multi-layer HD coating has been applied to lens elements to help minimize flare and ghosting for enhanced contrast, clarity, and color fidelity and a seven-blade diaphragm contributes to an aesthetic out-of-focus quality to benefit shallow depth of field imagery. Additionally, an SP Protect coating has also been applied to the front lens element to effectively protect it from dirt, oil, and finger prints.

The compact form-factor of this lens integrates Pentax's Quick-Shift Focus System, which allows manual focus control over the lens at any time, even in AF mode, for precise handling over the focal plane.

Prime normal-length lens provides a 35mm-equivalent focal length of 60mm, covering a natural perspective that is well-suited to everyday applications.
Slim, pancake-style lens measures just 0.6"-thick.
High-grade multi-layer HD coating minimizes lens flare and ghosting to enhance contrast and color neutrality.
Quick-Shift Focus System enables manual focus control at all times for precise handling that is well-suited to selective focus imagery.
Super Protect coating helps to protect the front lens element from dirt and finger marks.

    Pentax 40mm f/2.8 reviews

    HD Pentax DA 40mm f/2.8 Limited Lens (Black) is rated 4.6 out of 5 by 5.
    Rated 4 out of 5 by from Good quality image Paired it with my new K-5IIs, image quality is very close to a full frame format.

    Rated 5 out of 5 by from 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.

    Rated 5 out of 5 by from Good all-rounder 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.

    Rated 4 out of 5 by from 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.
