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...

sharp lens makes beautiful photos

  • 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.

Value for money 40mm optics, but mounting is tricky

  • Summary: It's a Pentax 40mm f/2.8 lens. Image quality is as expected of a prime lens. Looks really good if handled correctly. Mounting it to the K-30 is a real pain and tricky. I have an 18-55 WR and 18-135 WR lenses, both are quality lenses and mount easily in the first attempt. Value for money optics. Still a good lens.

Very light and sharp with fast focus

  • 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.

a functional lenscap

5 February 2013
  • Excerpt: This is the standard lenscap replacement for the Pentax DA-40 f2.8 lens that comes with some K-01 kits. I bought it because I had an $8 credit with Adorama I needed to use, and am always worried about losing this lenscap. So now I have a spare.
  • Pros: Durable, Lightweight
  • Cons: Poor Design

Excellent compact lens

  • Excerpt: This very compact lens allows me to use my SLR almost anywhere as I would do with a small point and shoot. I've used the DA 40mm XS on my old Pentax K10D that has now found a new live as a camera for vacation and any situation when you don't want to transport a big camera-lens kit. Because the Pentax bodys are small, it's easy to put it in your pocket. The 40 mm with the 1.5X factor is perfect for many situations (portrait, landscape...
  • Pros: Consistent Output, Easily Interchangeable, Lightweight, Nice Bokeh

Pentax 40mm f/2.8 XS SMC DA review by Marriott

Marriott, slrgear.com
17 June 2012
  • Summary: The beauty, fun and value of this lens is in it's tiny size, good IQ above 2.8, and its curiosity to others wondering "what the heck are you using there"? Don't misunderstand, at 2.8 it's quite sharp in the middle. My copy seems a bit better than the review sample while having similar characteristics. It does fall off at the edges and corners wide open, but I'm not really bothered by it at that aperture.
  • Pros: The usual: small, extremely light, (50g!), gets people's curiosity.
  • Cons: soft corners at 2.8 (but sharp center), build is just ok.

A fantastic, no excuses lens!

Howard A, B&H Photo
14 June 2012
  • Excerpt: I am just a photography enthusiast. The only things that are important to me in terms of lenses are how the pictures look and does the lens impede my shot. The first thing you'll notice about this lens is that it is tiny. It takes up almost no space in your bag and it weighs almost nothing. There is no reason not to bring it along on any shoot. It is so liberating to have this on your DSLR! The 40mm focal length reminds me of the 35mm Kodak Instamatic I had as a kid.
  • Pros: Consistent Output, Fast / accurate auto-focus, Lightweight
  • Cons: Tough To Attach

  • Summary: well worth the money. Received this lens with a pentax k-01 kit, and it outperforms a lot of prime lenses at 1/4 the size! LOVE LOVE LOVE IT!
