With newly developed, high-performance optics, this new lens measures only one inch (25 millimeters long) and weighs a mere 4.9 ounces (140 grams). Mounted on a Pentax digital SLR camera body, the lens protrudes very little from the cameras front panel, making it an ideal choice for carry-everywhere, instantaneous snapshot photography. This versatile angle of view produces natural images with a moderate perspective and an expanded depth of field (or a wide in-focus area), making it ideal for many different types of subjects and occasions, including snapshots, landscape, travel photos, and architecture. The DA 21mm incorporates a hybrid aspherical lens in its eighth optical element to effectively compensate for a variety of aberrations, which cause adverse effects on overall image quality. In order to assure high-quality image reproduction over the entire focusing range, it also features a floating mechanism, which is designed to adjust the degree of aberration compensation in relation to the focusing distance.

How often have I seen travellers crading a huge 72-filter size zoom like a drunk protecting his bottle. A lens this small, especially on one of the smaller Pentax DSLR bodies, makes an SLR pretty close to (winter) coat pocketable.
This lens has been criticised for having barrel distortion approaching 2.5%. My particular sample doesn't seem this severe. If you are concerned about this, learn how to correct barrel distortion in your imaging program. I find no fault with the DA 21's sharpness past f4. Shooting at low ISO's and at full resolution, you can do pretty severe crops and still maintain a decent file size.
I paid $429 for mine new at B&H two years ago. The prices I am seeing now are ridiculous, even for a lens this good. These small lenses are what drew me to Pentax, but I would not have bought this or any other DA lens at these latest prices. Pentax is in no position to be shooting themselves in the foot.
Wanting more length is not a problem, as the DA21 takes high enough quality pictures to allow me to crop until I get what I want. I can't do anything about width, but 21mm was good enough for me in cities such as Hong Kong and Seoul. Also, in the times when I needed to take hand-held self portraits with my significant other, the DA21mm performed flawlessly. Try taking one handed self portraits with the DA* 16-50!!
When there isn't ample lighting, which is the case in most indoor photography, i do increase the ISO more than I'd like, and at that point, high ISO+slower shutter speed means crap photos. But I'd rather carry around my monopod than carry around my FA50mm. With my monopod, i can user a lower ISO and get results i like.
In short, a lot of rambling later, the DA21mm is just about the perfect walk around lens. I would take it over the FA35mm too. Just because the significant other hated the fact I couldn't take self-portraits with the 21mm:)
Combined with the Pentax K10D, this is my sketchpad -- the kit I carry when I don't carry much.
