Average Reviews:
(More customer reviews)I was one of those holdouts that carried lots of prime lenses, disdaining zooms as "a compromise". No doubt, I missed some fine lenses because of this.
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 grouch 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!

The compact, high-performance, interchangeable smc PENTAX-DA 16mm-45mm F4 ED AL lens features a 3X zoom ratio with focal lengths covering ultra-wide to moderate-telephoto ranges for the angle of view equivalent to 24.5mm-69mm in the35mm format.The DA-Series features a responsive "Quick-Shift Focus System" that allows photographers to instantly switch the focus mode from auto to manual with a slight twist of the focus ring. Coupled with a simple, functional design and the elimination of an aperture ring, this new mechanism considerably improves the camera's operability. The lens also incorporates an Extra-low Dispersion (ED) glass lens element and two aspherical lens elements for true-to-life image reproduction and overall size reduction. The image circle in DA-series lenses, including the smc PENTAX-DA 16mm-45mm F4 ED AL, is designed to perfectly match the 23.5mm x 15.7mm size of the CCD used in PENTAX digital SLRs to optimize camera performance. The new design also contributes to a drastic reduction in size, weight and production cost, compared to 35mm-format counterparts with similar specifications.
