A Lente Autofoco Pentax SMCP-DA* 50-135mm f/2.8 ED (IF) SDM é uma lente zôo telefoto de alta qualidade projetada exclusivamente para uso com câmeras SLR digitais Pentax. Oferece uma distância foca equivalente (no formato 35mm) de 75mm a 202mm. Esta ampla cobertura é ideal para uma variedade de aplicações telefoto, incluindo retrato, esportes e cenários.
O círculo de imagem nas lentes da série DA foi projetado para se adequar perfeitamente ao tamanho de 23,5mm x 15,7mm do CCD usado nas SLRs digitais da Pentax para otimizar a performance da câmera.(*) Esse design também contribui para uma drástica redução de tamanho, preço e custo de produção, comparado com lentes do formato 35mm com especificações similares.
Lentes zoom Pentax DA* (DA-Star) vêm equipadas com o sistema SDM, que assegura operação auto-foco mais suave e mais silenciosa usando um motor supersônico integrado. Quando montada no corpo da câmera digital SLR K10D, o modo de foco é automaticamente trocado para autofoco assistido por SDM. Quando montada em corpos de câmera SLR digital Pentax mais antigos, o modo autofoco convencional usando um motor montado na câmera é selecionado.
Como todas as lentes Pentax, esta lente é tratada com revestimento smc para a máxima transmissão de luz, definição nítida e imagens de alto contraste. Além disso, o revestimento SP (Super Protective) feito de composto de fluoreto especial foi aplicado na superfície frontal da nova lente através do uso de um exclusivo processo de evaporação. Em conseqüência disso, a lente oferece uma excelente performance que repele óleo e água e facilita a limpeza caso a lente seja manchada acidentalmente por impressões digitais ou cosméticos.

In addition to the Canon EOS Line, I also purchased a Pentax K20D recently. My Pentax was failing in comparison with my EOS 40D with the 24-105 L lens. Compared with the Pentax and 3rd party zooms I had for it. Until I got this lens.
I wanted a professional caliber camera and lens to take with me on trips away from the studio and the requirements were to be durable, weather sealed, hi-resolution, and pro-quality imagery.
The focus is near silent, quick and very accurate, which is an accomplishment for a Pentax mount lens.
In a Zoom lens, this lens is a must-have to get that quality out of the K20D. Along with the primes (FA-77 ltd, FA-31 Ltd, DA-40 ltd) Color Rendition is similar to the Canon L-Series Lens. Great for skin tones. The contrast is very pleasing with more detail in the shadows and highlights than with the Canon 50-200 shooting the same scene with the same settings. This lens feels very nice in the hand with a sturdy feel. It's weather sealed. I have taken this lens to the beach, to the zoo and on several trips since I've had it. It takes professional caliber images, and it's the only zoom out there right now for Pentax that I can say that about. The composite body seems like it will be very durable. This is a nice lens with no sacrifices (as long as the range of 50-135 suits you)
I haven't tried the 16-50 zoom lens yet.
This lens covers a near perfect focal range for me in my travels. This also covers my portrait ranges that I use most (50-100) I prefer to use primes in the studio, but there are times I can't or don't want to or the situation calls for a zoom. I feel like I can use this lens professionally for portrait and glamour work when I do need a zoom (like I have been able to with the Canon 24-105)

Particle inside lens
The lens is very good. But the small particle was noticed inside. Luckily it isn't visible on photos.

Fairly fast lens with good range for travel photos other than landscapes 16-50 for those. Autofocus fast enough, and works well in low light situations. Can handhold without blur at slow shutter speeds. Somewhat heavy.

I use this lens for everything! The focal length range is just right for most activity and the f2.8 aperture makes it fast enough for most action. I've been using it for snapping photos of the birds at our feeder and whether they are stationary or in motion, it really has been great.

First things first, this lens is SUPERB. As an avid events photographer and prime lens user, I found myself stuck between practically desiring zoom capabilities and holding to my convictions that only prime lenses output optimum picture quality. My desire for zoom won and I got the DA* 50-135mm. I was wrong about only using primes! There is a lot of hype that surrounds this lens and ALL of it is warranted. It constantly surprises me and it consistently and effortlessly produces stunning, sharp as a tack images, shot after shot. It truly does feel like i'm working with a set of prime lenses. This lens is a must have for existing pentax uses, the perfect reason to upgrade to a K-5 and is every reason to invest in the Pentax system if you have not yet already done so. All in all, this pro-quality lens is as close to perfect for events and portraits as I could have ever hoped for.

The first copy I got has had Focus issues,
However,
When working this is one of the finest lenses both to handle and take beautiful pictures.
Lovely smooth bokeh and a highly useful 2.8 aperture
Recommend getting a warranty as there has been problems with the SDM motors later down the track

I'm full-time portrait photographer. I love fix lenses but wanted to buy something all-purpose to have one lens for outdoors photography. That lens is close to ideal ! Very sharp, light, all-weather. The only drawback is slow AF. Otherwise - great lens for all Pentax users.

so far i've not yet been able to do low light concert photography with it, but we did decide to take snapshots of our gameplay and with the faster lens, we could adjust the shutter speed to take surreal like "paintings" from the plasma tv game. :) great lens, a bit heavy, but that's how it goes.

Landscapes, scenics, sports, action, family-- really a very good multi-purpose short to medium tele-zoom. I use the DA* 50-135 in conjunction w/ the DA* 16-50. The 50-135 is small, light and f2.8 fast. But what's really nice is it has both internal zoom as well as internal focus. Build quality is excellent as is image quality. This is one lens I'm willing to carry for just about any purpose-- and it's weather sealed.

Comments about Pentax Zoom Normal-Telephoto SMCP-DA* 50-135mm f/2.8 ED (IF) SDM Autofocus Lens for Digital SLR:
I'm a student photographer and went with the Pentax K-r with the stock 18-55mm lens. Boy does this lens sure crank out great images.
The focus is tack sharp and quiet. It's not totally silent, you can still hear a soft "shh" when you look down the viewfinder and focus. The focus isn't the fastest either.
The quality of the build and switches doesn't show any signs of wear and tear in the months that I've had this lens. Be mindful of the lens weight though. It isn't exactly heavy, but it can throw off the center of balance on a camera like the K-r which is comparatively light.
I also stress tested the lens for purple fringing and came up with an excellent nightmare scenario, and even in the corner of the lens, at 50 and at 135mm, there was very minimal fringing.
Couple this with a 16-50 like I am planning, then I'd say I have a great lens foundation for my building skill set. A handful of primes and specialty lenses later, I should be set! IMO, a must have for every camera bag.

Comments about Pentax Zoom Normal-Telephoto SMCP-DA* 50-135mm f/2.8 ED (IF) SDM Autofocus Lens for Digital SLR:
I bought this lens to meet my need for super sharp images in a no-flash indoor sports setting-Volleyball. This is an astoundingly difficult sport to capture- the action is very fast and the court is much smaller than B-Ball or Hockey, say. The focal length range is ideal for the long side of the court, and the f2.8 (with a little push)seemed like the best possible choice out there. Image quality is superb, prime-level sharpness, color rendition and especially saturation makes me think of 1/2 stop under Kodachrome. A minor issue (to me) was inertia- it takes a bit to swing this hunk of glass around fast enough to follow VB action. I don't mind the inertia issue, I just mention it. The issue that left me disappointed was the speed/precision of the AF; I have quite a few "would've been" great shots from the last tourney. I eventually started using manual focus "field focus" techniques and waiting for the action to come to me. With more light, I could've stepped down a click or two. With time I'll get a better feel for how best to use the lens; but I'd say potential buyers need to recognize this is a pro-quality lens that performs best in skilled hands. It is NOT an all-forgiving kit lens; on the other hand it can produce truly amazing results. I can count individual hairs on a player's arm from baseline on the other side of the net- AND see the shade of her green eyes!
