Pros: IQ, size, build quality
Cons: Fussy lens cap
Sharpness: 9    Aberrations: 9    Bokeh: 7    Autofocus: 10    Handling: 10    Value: 9    New or Used: New    Camera Used: K100D, K20D, K-x, K-30   

I use this lens far more often than I ever thought I would use a 15mm. Images are beautifully rendered even wide open. Great for portraits in tight spaces if you are careful -- the distortion control is very, very good. I find the size to be just perfect on a DSLR. It handles amazingly well.

I prefer this lens over the DA 21/3.2 for sure. It is a little longer and heavier, but they are both very small lenses. The focal length is substantially wider than the 21, which makes it a better fit alongside a 28, 31, or 35.

The only issue I have with it is the screw-in lens cap, which is just kind of annoying. I'd hate to put a plastic press-on cap on the front of it though, so I live with it. It is a very small price to pay.

Pros: small, sharp, love the hood, love the focus ring
Cons: screw in cap, I change another snap-on cap
Sharpness: 9    Aberrations: 9    Bokeh: 9    Autofocus: 10    Handling: 10    Value: 7    New or Used: New    Camera Used: K30   

One of the best lens I have.

Very nice focusing ring and feels good.
I can put a regular 49mm pentax filter in front and no problem with using the hood.
I don't get vignetting until I put 1 more ND filter on it

I don't own it for a long time but I prefer it way more than my sigma 10-20, and my sigma 12-24on FF.
If you don't need to go that wide, this is the lens for you.

Pros: Superb build, light, excellent IQ at F8
Cons: price, but you get what you pay for
Sharpness: 9    Aberrations: 9    Bokeh: 7    Autofocus: 10    Handling: 10    Value: 7    New or Used: New    Camera Used: K5   

I have had this lens for almost 2 years and is a companion to the 40 and 70 for walk around. It performs best at F8 and is a joy to use. It is a quality piece and the pictures it produces are stunning. I use this a lot for waterfalls and landscapes. It got a lot of use a couple weeks ago in the Mayan Riviera. The ruins were detailed and the colors are typical Pentax.

I would recommend it for anyone that wants a quality wide angle, especially if you like to travel light.

Pros: Low aberrations and distortion, superb in backlit conditions!, good sharpness, compact, fun to use, pictures look great!
Cons: Wobbly built in hood, sharpness at longer distances?, a bit pricey
Sharpness: 9    Aberrations: 10    Bokeh: 7    Autofocus: 7    Handling: 7    Value: 7    New or Used: New    Camera Used: K-5, K-x   

Pros:

Most important: this lens is great fun to use and the pictures look great. It's huge fun for dramatic and distorted perspectives. Can be great for street photography, and for architecture too. (It guess it might do good landscapes too but personally I prefer longer lenses for that.)

Sharpness at close distances is stunning, though at longer distances it could perhaps have been better? But perhaps I'm asking too much resolution-wise, details are after all depicted on a very small scale with 15mm at long distances.

The best aspect of this lens is for me how great it is in backlit and sidelit conditions. You almost have to provoke flare to get any, and colours and contrast remain great. I'm quite impressed with this lens in this department. This is really important for such a wide angle lens because you often have bright lights in or just outside the frame.

I haven't noticed any CA or PF at all. Distortion is low for such a wide angle and easy to correct in PP.

I really appreciate the compact size and good build quality too (apart from the hood, see below).

Cons:

The built in lens hood is too flimsy for my taste, it's not smooth but easily wobbles when you extract and rectract it. And it's easy to push in by accidental touch. I guess it's difficult to build with tighter tolerances in such a compact lens, but I think a snap on or even screw in would have been better. Or a permanent one.

Many seem to be annoyed with the screw on lens cap, and it is a bit silly. But it's no big deal for me since I leave the cap off for as long as I'm out shooting. Don't know why the hood and cap are lined with velvet though, it attracts dust.

Price is a bit high, but then again extreme wide angles don't really come cheap. (I got it for about $700 and that's a bargain in Sweden, typically it's about $1000...)

Pros: Compact, excellent subjective results.
Cons: Soft corners and distortion.
Sharpness: 7    Aberrations: 8    Bokeh: 6    Autofocus: 10    Handling: 9    Value: 8    New or Used: Used    Camera Used: K10D   

First, this lens is in the "just buy it" category. I waffled for several years, even trying out a Tokina 12-24 F4 in Nikon mount as a half-price proxy, mainly because I was unsure about whether I would actually use of the ultra-wide focal length.

Well, I can tell you two things:

1. The Tokina actually performs better in a lens test evaluation. It's sharper in the corners and there is less distortion. But the DA15 produces stunning results, which the Tokina zoom cannot match.

2. Do not underestimate the advantage of a compact ultra-wide. The zoom lenses are not huge, but they completely change the way you handle the camera, and how often you take it out. The DA15 is far, far nicer to shoot with.

I don't use the DA15 that often, but I'm very glad I have it.

Pros: Flare resistance, starbursts, size, quality
Cons: Maybe the cap
Sharpness: 10    Aberrations: 10    Bokeh: 7    Autofocus: 10    Handling: 10    Value: 10    New or Used: New    Camera Used: K-7   

Astonishing flare resistance. No trouble at all to include the sun in the scene.
In my mind, this lens is the number one reason to shoot Pentax (and APS-C for that matter).

Starbursts are perfect and very easy to produce, from about f/5.6 onwards.
Haven't seen any purple fringing, except in very out of focus areas, which is rare in wide angle lenses.
Autofocus very zippy / almost unnoticable.

Very close focusing. It is possible to get (somewhat) out of focus areas if you get close enough to the subject, but they stay a bit busy, which is hardly surprising for the focal length.
Colour, contrast, sharpness seem on par with my 35 limited - they make a nice pair. f/5.6 to f/8 is retina-slicing-sharp at any focal distance. Skies look rich and deep blue.

I like the pull out lens shade - very convenient. Screw on/off cap is too fiddly for me - I'm worried about scratching the lens or damaging the filter thread, so I'm now using the Pentax 31491 cap, same as is standard on the FA50.

Only 'weakness' of this lens is that you don't want to shoot a landscape at f/4, because it doesn't produce a perfectly flat imaging plane like a macro lens would. However f/4 is perfectly good for close ups.

In the pictures below detail is completely retained right next to the sunburst!!

There is little I can add to the other reviews, this is a great lens, and a must have for a photographer who likes a compact system. Shot an art exhibit opening with numerous point light sources—no flares or distortion and a minimal "wide-angle effect" . It does exhibit some coma wide open at the corners. One note: use an empty 49mm filter ring as a spacer to enable the use of filters which won't fit within the retracted lens hood. You can usually add one filter without much vignetting.

I love this lens! This lens is one of the main reasons I decided to switch to Pentax from Sony Alpha. It is well built and worth it's current price tag I feel. The best thing about this lens is it's amazing color rendering and contrast! Not to mention it's amazing flare resistance and amazing sunburts at f/8 or more. It's nice and sharp, although as other reviewers have mentioned, it is can be soft in the corners when wide open. This lens is simply the best ultra wide lens on the market right now! Here's some examples:

Twin Lakes sunset near Mammoth Lakes California-


Classic sunburst with the 15mm-

I haven't have much extensive use for this lens, So I will reserve my review for now.
But I wanted to mention that the 49mm Marumi thin slim super DHG CPL will work on this lens without problem, while the "brass" version of this CPL, the "Brass 49mm CPL Digital Pro Filter Lens Marumi MC Thin Slim" will not work on this lens as this filter has a ring that is slightly larger than 49mm.

Hope this info helps.

I just got it and took few shots indoor and love the results already, looking really good. Very sharp, colors are really nice and overall I believe this will be my main lens.

Pros: Lives up to hype
Cons: Built-in hood
Sharpness: 10    Aberrations: 9    Bokeh: 9    Autofocus: 9    Handling: 9    Value: 9    New or Used: New   

Looking through the images posted from this lens on this site, it's hard not to suspect that Pentaxians are doing some of their best work with the DA 15; and while the photographer bears the ultimate responsibility for the final product, a superb lens can inspire a talented photographer. And I believe that's what we see in spades with the DA 15.

The DA 15 provides as good image quality as you're going to get at this focal range with a Pentax DSLR. It's as sharp as my K 50 f1.2 and DFA 100 f2.8 WR, two of Pentax's sharpest lenses. It produces the rich, distinctive, eye-catching colors that the best Pentax lenses are known for. The microcontrast of the DA 15, combined with the resolution, gives images a degree of clarity and vividness that appears only considerably more expensive lenses. And this is all provided in a compact, exquisitely engineered package. The built-in hood can be a nice additional feature, provided you don't need to use square filters. Then it becomes a bit of a nuisance.

Some complaints have arisen over the corner resolution of this lens. In the more than half a year use of the lens, I haven't run into any serious problems with corner resolution. Are the corners less sharp than the center, even when stopped down? Yes. But it must be kept in mind that the center is so sharp that a loss of resolution toward the corners is not terribly significant. The corners have plenty of resolution for all but the most uptight photographers, as can be noted in the following 100% crop:



The DA 15, thanks to its excellent flare control, has developed a reputation as a great lens for "sun" photography:





It also acquits itself very well in images that don't include the sun:

Pros: Sharpness, image quality, solid construction, built-in hood
Cons: What's up with that lens cap, anyway?
Sharpness: 9    Aberrations: 9    Bokeh: 8    Autofocus: 10    Handling: 10    Value: 9    New or Used: Used    Camera Used: Pentax K-5   

I rented this lens so I could use it while taking photos of an event for a local museum, and after using it in a variety of different settings, I wish I had just bought it outright. I can't go in-depth since I haven't used this lens much, but I am absolutely impressed by this lens's indoor performance. Combined with the K-5 or a K-r the DA15 was able to focus very quickly even in very dim conditions. Of course, there is distortion (it's a 15mm lens!), but the distortion actually isn't bad. It's very easily corrected for in Lightroom, though it's perfectly fine to leave it as is in many situations. Images were very sharp, even at f/4, with very little corner fringing or blur.

I've also used this lens to take some portraits of people, and if they don't mind you getting reeeeeally close to them, you will get excellent results.

So yeah, I really need to buy this lens when I can afford one. It's built for landscapes but can be adapted to any situation for a unique perspective.

Pros: sharp, small
Cons: can't use lens cap with filter
New or Used: New    Camera Used: K-01   

This is a well-built, sharp little lens. I wish it was a little wider - 13mm instead of 15mm - but it's a great match for the K-01: at last a Pentax setup I can carry in my backpack!
I have a circular polarizer on the front, which means the lens cap doesn't fit and put a little sock over it instead... somewhat inelegant, but what does that matter?

Pros: sharp when stopped down, small size, great colours, quick shift

Sharpness: 8    Aberrations: 10    Bokeh: 8    Autofocus: 10    Handling: 10    Value: 9    New or Used: New   

great build quality, best use is obviously landscape

needs to be stopped down for best sharpness, the colours are great as well

best thing of all is the small size - best tradeoff in terms of FL + speed which i don't see a need for f2.8 for this type of lens

the screw cap is a bit annoying for me (as it was for the da40) and hence replaced it with a generic 49mm pinch cap (It does not scratch the front element)

Pros: Smaller light lens. Stylish, well made, one of Pentax's better designed in built hoods
Cons: Depending on your needs-not wide enough, lens cap
New or Used: Used    Camera Used: K-5   

Vanyager's review above covers a lot of points and I fear my own review will pale in comparison.

This lens is a very stylish and well made lens which takes great photos. I did find that it was not wide enough sometimes for what I wanted, and eventually sold it for a wide angle zoom lens. I like to take photos of rooms and places. I won't say architecture- that presumes I am a serious buildings person, and I'm far too UN knowledgeable to say that.

Size and weight is not so important an issue for me- after all, the K-5 already weighs750 odd grams, there's not much difference between 200+grams for the 15mm and, say 420grams for the tamron 10-24mm which I bought after, added to it. I am now thinking about getting the Sigma 8-16mm.

If 15mm is the right angle for you, then feel rest assured, it is a great piece of glass. The lens cap is a real pain though, and the first thing I did was put it back in the box and use a B+W 49mm pinch lens cap.

Regarding Resale value, in Singapore, where I currently live, it seems to be difficult to buy retail and is highly sought after on the second hand market. Within 45 minutes of me placing my advertisement selling the 15mm, a fellow Pentaxian had reserved it for a viewing, and 4 hours later it was sold.
