A lente XR Di de 28-300mm da Tamron substitui a popular versão XR LD Ultra Zoom e agora foi aperfeiçoada para incluir o design "Di" da Tamron. O design Di (Digitally integrated) é a designação da Tamron para lentes que possuem o design ótico aperfeiçoado que se adapta às características de performance das câmeras SLR digitais e também das câmeras de filme. Quando utilizada com câmeras SLR digitais tamanho APS-C (padrão), a lente oferece um ângulo de visão equivalente a aproximadamente 43-465mm, cobrindo a faixa padrão até ultra telefoto sem comprometer a qualidade ou a faixa de abertura.
Esta lente é ultracompacta e leve, com uma distância de foco mínima constante de 1,6 pé (0,5m) e uma ampliação máxima alta de 1:2.9. Os notáveis avanços foram obtidos através do vidro XR (extra refractive index) e o uso eficiente de lentes aesféricas. O tamanho é reduzido em 25%, o peso, em 27%, e o diâmetro do filtro diminuiu de 72mm para 62mm. Lente zoom "tudo-em-um", ideal para o uso em áreas internas e externas.

Comments about Tamron 28-300mm f/3.5-6.3 XR Di Autofocus Lens for Pentax AF:
This is the second Tamron Lens I have purchased. Tamron builds lenses which will rival any of the best known brands. As far as I know Tamron does not make cameras and concentrates on optics. They do a great job of making very high quality lenses. I am using this lens for landscape, architecture, and very close-up details. It is an all around great lens.
I mostly use a tripod so the slow f/3.5-6.3 is not an issue, but hand held has not been a problem.

Comments about Tamron 28-300mm f/3.5-6.3 XR Di Autofocus Lens for Pentax AF:
I was a skeptic when it came to purchasing an all in one lens. In fact I have been researching the my lens options for over 1 year now trying to decide if this would be a good use of my money. But, after planning my family trip to Florida I thought this would be the best trip to prove this theory wrong. And it worked!
This lens is perfect for an all in one lens especially when traveling with the family to Florida and wanting up close shots. Due to the crowds and quick movement through the parks, time is not always on your side to capture that awesome picture of your kids that some shots require. This was not the case with this lens. I was able to zoom in to Shrek and take up close pictures from "very far away". Family pictures came out beautiful and clear like my factory lens but, with a lot more options for zooming into the subject during the shot. Color patterns when reviewing from CS5 were perfect with each shot allowing the camera and lens to work flawlessly on the subject. I was able to take a picture of my kids with several characters capturing the moment perfectly with this lens. Having the zoom options available and not having to worry about switching lens to accommodate the crowd or location I was provided or limited to make each moment turn out brilliant. This lens captured wonderful pictures for my family and I to cherish for years to come. And most of all, my shoulder was saved not having to carry three different lens like I normally would.
Overall, I was a skeptic for the all in one lens, but after using this lens on our family trip, I will not be placing this it in a pouch for quite some time.

Dear friends,
This is really a good lens. This lens provides a wide zoom range, has a minimum length of 3.3" and weighs about 1 lb. It is not very fast with a maximum aperture of F 3.5 at 28 mm and 6.3 at 300mm but when used with a Pentax cameras the automatic focus works well under most lighting conditions. It has produced good images in most situations. Although it focuses to 1.6 feet throughout the zoom range, to provide a 2.9 magnification ratio at 300 mm.Overal we are pleased with the Tamron AF28-300 and would recommend it to anyone that wants one lightweight lens to cover a wide zoom range.

I chose this lens because I like to photograph my son playing baseball. Although the season hasn't started yet, I can tell by the photos I've taken so far that this was the right choice. Whichever side of the field I'm on, I'll be able to photograph my son where ever he is on the field. I'm looking forward to the season starting.

Comments about Tamron 28-300mm f/3.5-6.3 XR Di Autofocus Lens for Pentax AF:
since putting this lens on my camera, I have only had it off a couple of times and that was for getting a super macro shot that this one would not do. It is the perfect lens for me for a wide range of shooting. At full telephoto, I find I do need a tripod, but for those times when I don't have it with me, holding extra still usually makes for a passable shot.

I had an older Tamron 28-200mm film version and lost it in camping accident. Since I am now digital I upgraded to the 28-300mm XR Di. More power, much sharper image, much smaller, 62mm vs.72mm on the old lense. Great all-around lens.

Comments about Tamron 28-300mm f/3.5-6.3 XR Di Autofocus Lens for Pentax AF:
I bought a limited edition red Pentax K-x back when they debuted. I liked the idea of a unique color, but I was disappointed that most retailers did not offer the limited edition cameras (red, white, or blue) with multiple lenses. So, I got the stock Pentax 18-55mm lens and nothing more. Although the quality of the Pentax K-x (especially for the price) is great, but the stock lens offered less zoom than my old, previous non-DSLR camera.
I looked at purchasing a Pentax brand zoom lens but theirs seem to lose a lot on the close side, and to be honest I'm not a real photography buff and don't want to be changing lenses fifty times a day. What I was looking for was a good lens that still allowed me to shoot pictures at a normal (3-4') focal length, but added a lot of zoom. Per a recommendation from a co-worker, I ended up with this Tamron 28-300mm lens.
The lens is essentially plug and play, so if you're a dummy like me there's not much to getting up and running. The lens comes with a big "sun shade" that screws on to the end of the lens. It does a good job of blocking the sun in outdoor photos, but indoors it can block the stock flash, and putting on and removing the lens cap with it on is a pain in the rear too. I also picked up a clear filter for the lens, to protect it from scratching.
300mm zoom is pretty incredible. During a recent high school football game I was able to get some great photos without leaving the stands, and the 28mm close end is comparable to the stock lens' close focal length. It's not a macro lens by any stretch of the imagination, but at least you don't have to be 6+ feet away like with the Pentax 55mm-300mm.
I'm not a photography expert and I'm sure there are a lot of technical numbers I'm missing, but as a beginner/enthusiast I can tell you that this lens adds the range, depth and zoom to my Pentax that I felt the stock lens was missing. I do not carry the 18mm-55mm with me when I go out; I leave the Tamron connected 24/7.

Comments about Tamron 28-300mm f/3.5-6.3 XR Di Autofocus Lens for Pentax AF:
I used this with Pentax K100D. I did not have any issues. Most times it was good. sometimes during low light, the lens did hunt for light/focus, but that is expected with a 6.3 lens. Otherwise, given the cost I am happy with the lens. I took a few Moon shots too, and they came out great. The build is pretty sturdy too.

Comments about Tamron 28-300mm f/3.5-6.3 XR Di Autofocus Lens for Pentax AF:
I got frustrated when I missed the shot because I was changing lenses, so I wanted one that was more universal. I really like this lens because I can get the whole scene in one pic. and then zoom in on one point of interest in the next. It takes very sharp images and I rarely need to change lenses, unless I need a wider angle. I'm very satisfied with it.

Comments about Tamron 28-300mm f/3.5-6.3 XR Di Autofocus Lens for Pentax AF:
I purchased this lens as an all around lens because I was tired of lugging around 2 lenses to get the pictures I wanted. It is exactly what I need, and I am getting crystal clear shots! I shoot mostly indoors, in dim lighting, from the light and sound booth in the back of a theatre. This lens is wide enough to take in the entire stage, but gets close enough to catch the expressions on actors faces. The only thing I dislike about it is that it takes a few seconds longer to focus than my old lens, but I think I can deal with this once I get used to it.

Comments about Tamron 28-300mm f/3.5-6.3 XR Di Autofocus Lens for Pentax AF:
The main reason we bought the lens for our Pentax is we now don't have to carry a bag of lenses for different needs. We like the 300 mm zoom for bird photos. The auto focus is nice for first time users and occasional users. A friend bought one and highly recommended it. A good investment.
