Pentax SMC DA Series 16-50mm f/2.8 ED AL IF SDM Wide Angle Zoom Lens for Pentax Digital SLR Cameras
Amazon.com
Designed for exclusive use with Pentax digital SLR cameras, the Pentax DA* 16-50mm f/2.8 wide-angle zoom lens is a terrific choice for landscapes, portraiture, and just about any other application. The lens features a tightly sealed, weather-resistant and dust-resistant construction to enhance durability in rainy or dusty conditions. The lens's three aspherical elements and two special optical glass elements, meanwhile, help compensate for chromatic and spherical aberration, producing images with superior contrast, clarity, and edge-to-edge sharpness. And thanks to the lens's Pentax-original Quick-Shift Focus System, you can easily and instantly switch from autofocus to manual focus.

There was a problem filtering reviews right now. Please try again later.
The coating has been super durable and scratch resistant even after many cleanings in the field, and I eventually was perfectly happy to use the lens without any filter or protector (but I always use the hood to avoid accidental contact).
The optics are great, focus is good and fast, the Quick Shift ability is something I now take for granted and would miss in any lens system that didn't have it (the ability to manually focus the lens without having to change any controls, even when the camera is in autofocus mode).
Apparently some batches of this lens had problems with the SDM focusing motor but mine has not had that trouble, over many thousands of autofocus operations and shutter releases. I think one time it very briefly acted a little stuck, but I turned the camera off and manually turned the focus ring a little, then turned the camera back on and it was fine ever since. That was almost two years ago with no other problems yet.
It's large and heavy and significantly changes the balance point of the camera, but that also contributes to stability and thus good clear images. It does make it somewhat marginal to use an ultralight backpacking tripod like the cheap ones from Slik, but I have done so anyway; I just had to be careful with the head locks. The size of the lens usually prevents me from wanting to use it on the street (mainly the length... I feel most people will assume it's a long telephoto and that I'm snooping on them). For street use I hope to acquire a smaller prime eventually.
It was difficult to afford a piece of glass this expensive, especially when purchased at the same time as the camera body, but I'm glad I did. This is one lens that can make a big difference over the kit lens if you had to choose a single one to begin with.
Ammended 9/24 2009
The replacement arrived I tested it today using the same method and the alignment on this replacement lens was out of alignment in roughly the opposite direction by a similar amount, making the left edge significantly less sharp focused than the right. I returned it for replacement. We shall see what we get on the next try. I really would like to to get a properly aligned example of this lens that can provide images with a consistent focus left and right and top and bottom.
Ammended 9/29/2009
Amazon declined to send a third lens, offering simultaneously that getting two defective examples was very unusual, and strangely that, were they to ship a third, it would likely suffer the same defect. They volunteered to refund my shipping cost and purchase price, and recommended I contact Pentax. I will post clips from the center and each of the two extreme edges of the test image on this site.
It was very easy to alert Amazon and initiate a return. I really would still like to get a good one of these lenses. Apparently you do need some amount of luck to accomplish that.
My advice to anyone wanting one of these is, be prepared to test what you get, and do not order it a week before your big vacation trip expecting to have one arrive at the last minute that is good enough to use.

Da ich diesen Artikel schon einige Wochen in Gebrauch habe, bin ich der Meinung mir ein Bild davon machen zukönnen.
• Der Autofocus sitzt, ist sehr leise und schnell
• Die Blendensterne sind sehr gut
• Man hat fast keine Lens flare, auch sehr gut
• Der Brennweitenbereich ist hervorragend
• Und das ganze alles noch bei f 2.8
Also, was will man mehr?
Auch wenn es laut techn. Daten vor 10 Jahren entwickelt worden sein soll, ist es für mich eine Bereicherung.
Man könnte fast sagen, es ist ein “IMMER DRAUF OBJEKTIV“, vor allem im Urlaub, oder wenn man wenig Gepäck dabei haben will.
Von mir eine absolute Kaufempfehlung
映りとは、直接関係ない部分ですが、レンズキャップが、相当古い(20年以上)製品のが付属しておりました。今のキャップの新品を購入しなおしましたが、発売されていたときと、おなじキャップを、付属させるのが、こんなレンズならマナーでは、ないでしようか?
安物の、レンズでは、ないのですから。
