The lens that sold me on zooms is this lens, the 16-45 f/4 Pentax. The lack of distortion, the contrast, the fine color control, all finally convinced me that a zoom can perform some of the functions of a prime.
I've been using this lens for a while. In my studio, the 50mm primes have become the main portrait lenses with the digital cameras. But now, I'm not afraid to use a zoom lens on a job. A big step for me!
It extends quite far when zooming, a fact I don't like, and for those who care, the on-camera flash is blocked by the lens hood (I use studio strobe, so it's of no import to me). As a modern lens, it has a polycarbonate barrel (they don't seem to be inclined to make zooms in the Lmited series. Too bad).
If I could use it on the film cameras, I probably would. No aperture ring means it's definitely meant for the current cameras.
Despite all that, I highly recommend this lens. It's a great "walk around" lens, going from very wide to moderate telephoto (remember, it's for the APS-C sensors). Image quality is astounding to an old woman who loves primes, and even for a lens in general it's right up there.
If you're faced with the choice of the kit lens or this lens, take the 16-45. If you are serious about your craft, or you make a living at it, it's well worth the price!
But at this price point it's a gem. The build is decent, and by using plastic instead of metal, putting the AF motor in the camera rather than in the lens, limiting the aperture to f/4 and the zoom range to 3X, Pentax kept the lens light and small. It's not expensive, it has a constant aperture, autofocus is fast and accurate, and (most important) it's optically excellent.
I already have the Pentax DA* 50-135/2.8, a beautiful zoom, and thought of buying the matching DA* 16-50/2.8, but I was put off by reports of poor quality control in the 16-50. So instead (and for half the price) I bought a 16-45. When it arrived I tested it by photographing a tabletop still life, including a test pattern, with my Pentax 21mm, 31mm and 40mm Limited primes at all apertures from f/4 through f/16, then making the same photo with the zoom at the same focal lengths and apertures. In almost every case the 16-45 matched the primes for center focus and sharpness, even at f/4.
Yes, the primes are better -- they have better corners, less vignetting, more overall contrast, an indefinable "snap" that gives the primes what I think of as the Pentax Look. And yes, the zoom does have an optical flaw: blue/yellow fringing where bright and dark areas are juxtaposed. (Seldom a problem, but it's there.) I'm hanging on to my primes.Read more ›
I'm not one of those people who photographs charts. But I've a LOT of experience looking at real world images. In fact, as long as the lens seems to be working I don't really pay attention to it. However, in this case, I was shooting some photos of rocks along the Maine coast, from a tripod, and I decided to try to use a few Pentax prime lenses--a 40mm SMCP DA 2.8 and the Pentax FA 50mm 1.4--just to see if zooms had improved. All shots were in the 35-60 mm range, around f5.6-f8. When I uploaded these images into Photoshop, I was flabbergasted. The 16-45 mm gave nicer color and was at least as sharp as the two primes. Since then, I've had occasion to compare it against my Pentax DA 14mm 2.8, and I haven't noticed any real-world difference at the wide range either. But it's the fact that, if there were a difference, I would have to look really, really hard to see it that impresses me!
I find that I use the !6-45 more than any other lens that I own. I purchased it as an "upgrade" from the kit lens.Read more ›
On a film camera, there's vignetting when you zoom wider than 21mm - but that's a nice special effect, a sort of semi-fisheye at 16mm. Also, using the supplied lens shade isn't a great idea when shooting with 35mm film cameras, as the vignetting starts early.
Overall, this is a super lens, the best zoom I've owned.
11/2007: I've been using this lens with a K100D with great results. The tone is if anything more concentrated on a digital body - though for some reason the slight underexposure trend does exist with digital but not film. The lens has decent close focus ability - your shots of kittens and flowers come out awesome!
I recently bought the 43mm Limited, and while it has greater resolution and tonality, and does better in low light, on a photographic (rather than pixel peeping) level the 16-45 is in the same league. I still highly recommend this lens as the best medium zoom value that Pentax offers.

LOVE this lens. It is the FIRST DA lens, and the design is jarring because it extends on the short end of the zoom... WEIRD, but this lens has legendary sharpness above 4.5. Read morePublished 7 months ago by Pentax Camera Guy
Bought used through Amazon but this works PERFECT on my Pentax K3. This is now my go to lens due to the clarity.Published 8 months ago by Mike Taylor
Excellent quality. The body seems to be mainly metal. Lens is sharp throughout the range. Zoom seems to feel lose, but then again I bought mine used so that may be the issue. Read morePublished 19 months ago by Chris

This is quite a nice lens in all respects. It consistently produces the famous Pentax colors and provides much improved clarity over the 18-55mm kit lens. Read morePublished on June 26, 2013 by Prodigal Knot
