Comments about Pentax SMCP-DA 40mm f/2.8 Limited Series Autofocus Lens:
Used with my Pentax K-5 DSLR, this is a fantastic travel lens due to it's unbelievably small size. Nice bokeh and sharp wide open, it works well for portraits and as a general purpose walking around lens. As a set, the 21mm Limited and this 40mm Limited together provide what I need when travelling.
The only thing that is not great is the strange combination lens cover/shade - you have to unscrew a small cap which takes a few seconds, not great when in a hurry. This is the only reason I am not giving this lens a 5 star rating.
Highly recommended.

I use this lens with my K5. It makes my camera very compact, ideal for street photography. But it's very versatile and can be used for almost anything (with some compromises...)

This "pancake" is ideal for indoor and outdoor scenes! Its main advantages (IMO) are: lightweight, compactness, sharpness.

Comments about Pentax SMCP-DA 40mm f/2.8 Limited Series Autofocus Lens:
When a minimum of camera gear is required and used with a K-r you cannot get much more compact than this in the DSLR world. The lens body is very nicely crafted out of all alloy metal components in Pentax's Vietnam factory - and don't be put off by the country of manufacture, it is top notch in every way.
The lens bag supplied is Japanese made leather with a neat drawstring and also very classy.
I won't go into specific performance information as it has all been described before by other reviewers other than to confirm that it works a treat with both my K-r & K-5. AF is fast, accurate and not very noisy - the screw drive will probably last a very long time.
If you don't like the lens cap supplied, plastic 49mm ones are readily available and cheap. My preference is always to attach a UV filter to a quality lens anyway, so this in combo with a plastic cap means its well protected and only adds a little extra length.
Things not to like - none that I can think of

Comments about Pentax SMCP-DA 40mm f/2.8 Limited Series Autofocus Lens:
I purchased in one time the three pentax pancakes, and, the principal thing that motivated me for get the pancakes, is this lens.
That will quickly become my main normal lens, the size, the construction, the look of the lens is amazing! Of course, the quality, colors, sharpness of the pictures taken with the pancake lens.
If I have to say one cons, its about the lens cap. I like it, and I know the way it works before the buy of the lens, but I think that for the price you pay for the limiteds, it would be nice if all of them come with a normal cap, when you intend to not use the hood.
Sorry my poor english

Comments about Pentax SMCP-DA 40mm f/2.8 Limited Series Autofocus Lens:
First and foremost, this is the coolest and tiniest lens you will ever use. It is beautifully built and incredibly solid. This impression is amplified by the solid metal screw-on hood, that both restricts stray light and protects the lens. Being able to screw a 30.5mm filter into the INSIDE of the hood affords further protection without spoiling the pancake lines of the lens at all.
I am probably the only person in the world who actually likes the metal screw-on lens cap; when in place the impression is of an impregnable bomb shelter. Yes, the cap is a little slow to remove (just over two full turns are required), but that suits my methodical approach. If you are walking round with this lens on your camera looking for random opportunities, you should leave it off. The lens is well protected by the hood anyway.
The only two disadvantages of the tiny pancake length of this lens are (i) the focus ring is very thin and takes a little getting used to; and (ii) there is no room for a depth-of-field scale. However, neither of these is a major issue.
Auto-focussing is fast and accurate on my K-5. I like to use it with spot centre-auto (or manual) focussing to get the best out of it.
Although not particularly fast for a mid-focal length prime, it is important to recognize that the Pentax DA 40mm f/2.8 is sharp wide open. I have no compunction in using it at full aperture, which would not be the case for many a fast standard lens. And of course, it really is fast compared to the 18-55mm kit lens which allows only f4.5 at 40mm.
By reputation, the pancake lens designs display very even sharpness across the frame, and that is certainly the case here. I have not yet seen any CA, though I haven't specifically tried to provoke it yet.
But for many people, the big question associated with this lens is "What do you use a 40mm (60mm equivalent) lens for?" It is a little longer than the old standard 50mm lenses on 35mm film cameras, and a little shorter than the short telephotos used for portraiture. I have taken a little while to come to terms with this issue, but am generally pretty comfortable with it now as a walk-around lens. I sometimes feel the need for something a bit wider but hey, that's what a SLR is for. Change lenses. The 40mm is also very natural for full upper body portraits.
Although certainly not a macro lens (minimum focus is 40cm and maximum magnification is 0.13), I have found this lens does a great job with flowers and other still life. The bokeh is smooth and unobtrusive.
All in all, this lens is a real favourite. I can see myself using it as one of my main lenses for years to come.

Like other people say, it's sharp, very good color, fast in AF, small, well made and visually attractive on my K-7.
I gave it 4 stars only because DA70 that I have is a bit better. This lens deserves 4.5 stars.

Nice sharpness even wide open, very usable in low light. It's next-to-nothing presence in my camera bag means I'm that much more inclined to go out and take photos - truly the best quality in a lens.

Reliable lens, good as a default. Extremely small (probably the smallest lens on sale). It is expensive and the lack of zoom is difficult to get used to. Results are excellent.

Comments about Pentax SMCP-DA 40mm f/2.8 Limited Series Autofocus Lens:
Great lens. Makes me much more likely to get out and take pictures if I'm not carrying around a big lens. I can put this on my K-R and stash it in my backpack for a hike very easily. It's also much faster and image quality and speed is better than the kit zooms. I have a couple of these limited lenses and the build quality is very high. They all have unusual lens caps. This one is small and screws in. I can see losing it but the weirdness is part of the charm.

This lens is absolutely a must-have for any Pentax shooter. The focal length is an interesting sort of in-between, but it works out as a fantastic walk-around lens. Image quality is fantastic, pictures are sharp and vibrant. Nice metal construction. The lens hood/cap design is a little strange, but not unmanageable.

Great lense...the focus is great...blurs out everything just enough. Takes very crisp fotos. Would def. buy again. Great as a everyday lense
Comments about Pentax SMCP-DA 40mm f/2.8 Limited Series Autofocus Lens:
Everyone who uses this lens is confused by the hood. The screw on lens cap is fiddly... etc etc.
This lens lives on my camera, unless I want to use something else. It's so light and shallow that your camera will hang level from your strap rather than being pulled down by even the 18-55, which is a huge improvement when carrying over your shoulder. The size of the overall package is something that can't be matched my any other manufacturer... it's so small that I use a neoprene body case over the lens as protection when I'm carrying the camera.
I use UV filters over all of my lenses all the time, and if you put a filter in front of the hood, or between the hood and the lens, you get a bad vignette. In the manual for the pentax lenses, however, it suggests something specifically for this lens that is a perfect solution. A 30.5mm filter will fit INSIDE the hood screwed in from the back. This is a fantastic solution.
