Pentax SMC DA* Series 50-135mm f/2.8 ED IF SDM Telephoto Zoom Lens for Pentax and Digital SLR Cameras
Amazon.com Product Description
Designed for exclusive use with Pentax digital SLR cameras, the Pentax DA series 50-135mm telephoto zoom lens makes it easy to capture close-in sports shots or intimate wildlife photography. The lens is distinguished by its aspherical elements, special optical-glass elements, and original glass coatings, which help produce a high contrast, unmatched clarity, and edge-to-edge sharpness.

| 56 of 56 people found the following review helpful  One of the best Pentax lenses ever!, By This review is from: Pentax SMC DA* Series 50-135mm f/2.8 ED IF SDM Telephoto Zoom Lens for Pentax and Digital SLR Cameras (Electronics) After anxiously awaiting the new DA* series of lenses, I bought it the day it was released. I had to photograph the Ujena Bikini Jam in Puerto Vallarta, Mexico and KNEW that I needed the benefits of a tightly sealed, weather proof lens because of the intense humidity. When I first mounted the lens to the body of my K10D (after updating the firmware of course) I was surprised at how incredibly quiet the motor is. I've never had this experience with any lens I've owned. I'm so used to the slight "whir" sound that lenses produced, it was hard for me at first to tell if it was working! The lens focuses quickly and accurately. The lens is nicely finished with nice rubber ribbing on the barrel. It accepts 67mm thread size filters. There may be a temptation to get a standard type Skylight filter. Spend the extra money for the Super Multicoated type. After all, if you spend nearly $1,000 for a lens, why would you skimp on a lower priced filter? The manual focusing mechanism turns freely after...

There's no mistaking that this is professional glass. For portraits and non-flash situations like stage performances, I wanted a lens that was top-notch in sharpness and overall image quality. According to the specs and the various reviews, this lens delivers...and that's why I bought it. Now the bad: I got a bad copy. When you point your camera at the intended subject and press the shutter, you expect the autofocus system to nail the focus, at least the vast majority of the time, especially with an expensive lens like this. Even a basic point-and-shoot is pretty reliable in that regard. However, not so with the DA* 50-135 copy I received. The majority of my shots are slightly off-focus, enough to not only cancel out the superior sharpness qualities of this lens, but to also ruin what would othewise be an excellent shot. This problem occurs in all types of shooting situations and camera/lens settings. What is... Read more 28 of 29 people found the following review helpful  Great Outdoor Lens! (updated March 2nd 2012), By Amazon Verified Purchase This review is from: Pentax SMC DA* Series 50-135mm f/2.8 ED IF SDM Telephoto Zoom Lens for Pentax and Digital SLR Cameras (Electronics) When I first got this lens, my initial thoughts were "wow, this thing is gorgeous". I love the gold highlights, the green line near the mount, and the massive zoom and focus rings. The large front element makes this lens look like it means business. This thing looks fantastic.On my K-7, this lens is perfectly balanced. The large zoom ring means the lens has a wide range of space to support it, so I suspect it would be well balanced on just about any Pentax camera. That zoom ring feels smooth, with a good amount of resistance. The focus ring is very similar, it's even larger than the zoom ring. It also has a fairly smooth motion with good resistance, although I found it felt kinda "dry" initially. Nowhere near the smoothness of my Super Takumar 50mm F1.4's focus ring, which is buttery smooth. It also has a super-long 130 degree sweep, which would be great for manual focusing but is far too long for an auto-focus lens. One oddity I hadn't experienced with a lens... Read more |
