Product Description

Color Name: Black

From the Manufacturer

With a 7.1X zoom ratio covering focal lengths from wide to long telephoto on consumer DSLR (APS-C) and full-frame formats, this is an ideal lens for sports action, travel photography, and creative expression. It delivers outstanding image quality over its entire range, down to 0.49m (19.3") (1:4 at 200mm) and it weighs only 354g (12.5oz.).

High-magnification zoom

AF28-200mm F/3.8-5.6 XR Di Features

Digitally Integrated (DI) Lenses for Top Imaging Performance
Tamron has made this lightweight, compact high power zoom lens available with the Di optical system with improved multi-coating for digital SLR cameras as well as film cameras, further enhancing its ease of use and popularity.

Extra Refractive Index Glass (XR)

Special glass for better performance and more compact lens designs

Extra Refractive Index (XR) glass can bend light rays at steeper angles, thereby decreasing the physical length of the lens while enhancing imaging performance by minimizing optical aberrations. This has allowed Tamron to develop a line of shorter, smaller-diameter, lighter lenses without sacrificing lens speed, and actually upgrading image quality compared to older designs. XR glass is costlier than conventional glass but it yields enhanced optical power distribution, making possible many of the outstanding and innovative lens designs that bear the XR designation. XR glass, with its superior light-bending power, makes it possible to design a short-barrel lens with the same light-gathering ability (aperture value) as a long-barrel lens—even with a smaller lens diameter. By using this principle Tamron has been able to shorten the length of the entire optical system and produce lighter, more compact lenses of the same speed, and also to provide greater zoom ranges in lenses that are much more convenient to carry by hand.

Internal Focusing (IF) System
Internal focusing provides numerous practical benefits to photographers including a non-rotating front filter ring that facilitates the positioning of polarizing and graduated filters, and more predictable handling because the lens length does not change during focusing. Even more important, Tamron’s Internal Focusing (IF) system provides a much closer minimum focusing distance (MFD) throughout its entire focusing range. In addition, IF improves optical performance by minimizing illumination loss at the corners of the image field, and helps to suppress other aberrations that become more troublesome at different focusing positions.

Aspherical Lens Elements (ASL)

Aspherical Lens Element

Tamron uses several hybrid Aspherical lens elements in many lenses bearing the Aspherical designation. These innovative optics allow us to achieve the ultimate in image quality, and at the same time produce lenses that offer remarkable zoom ranges in extraordinarily compact packages. By perfecting theses cutting-edge advances for series production, Tamron has advanced the state of optical design, and virtually eliminated spherical aberration and image distortion from the high-power-zoom series.Through the effective application of Hybrid Aspherical Technology, one lens element can take the place of multiple elements without compromising performance. This is what allows us to produce remarkably compact long-range lenses that deliver a uniformly high level of image quality at all focal lengths and apertures.

Zoom Lock (ZL)
Another original Tamron mechanical engineering concept is the Zoom Lock (ZL), a simple convenience feature that prevents undesired extension of the lens barrel when carrying the camera/lens unit on a neck strap.

If you are looking for a decent walkaround that does 95% of the ranges, and hate lugging loads of lens with kids for zoo trips or travel, this will be perfect. Folds to a amazing skinny size that is even smaller than the Sony Kit lens! Big PLus- Pictures actually turned out better than the kit lenses after some workouts.

I did some research before buying this lens and read about the struggling at 200mm. I verify it does struggles, but not something as unbearable as some made it out to be. Maybe we are more impatient in this age, and cannot tolerate a delay of a split a second. If you can bear with your 70-300, this will not be an issue for you.

However, please note that although it says F3.8, your camera will show maximum of F4.0.. According to the Tamron Customer Service, this is inherent for Sony Cameras only; so don't be alarmed..

Sans the prime lenses and CZ, this's gotta be the best purchase I've made. And it is dirt cheap (<150)!! I'll highly recommend to novice and pros. Try it and you'll soon dump your kits like I did!!

This is a solid excellent quality lens that will work on both your conventional and digital cameras. The price was very good, so buy if you can get a good deal, and are not worried about having the latest model!

This may be a slightly different lens review than most would write, but maybe someone will benefit from my experience. I was as interested in weight and handling as I was absolute image quality. My search was for an all-around and relatively light weight lens.

When I finally ordered this lens, it was after a pretty long internet search for something that would handle well and be more manageable on my relatively small a55 Sony camera. I already had a Sigma 18-250mm that is simply a GREAT lens. I enjoy using it, but not on an everyday basis. The Sigma weighs 22oz alone. When mounted on my camera, the total weight is 40oz or 2.5 pounds. Believe me, that's a load hanging around the neck. It takes some of the fun out of a day at the zoo or other activities where you are carrying the camera any distance. My first choice for a "walk around lens" was a Sony 55-200mm. It's the lightest long zoom available that I could find. By all reports, the Sony is a great lens but I reluctantly decided the 55mm on the short end was just not wide enough to make it an all-around lens.

I finally found this Tamron 28-200mm. The 28mm is wide enough for my use and the weight is only 2 oz more than the Sony. It feels great on the camera. At only 3" long, it balances so much better than my Sigma and is a pleasure to use. It feels like it was made for the Sony a55!

Initially, I thought I had a problem. I tested the Sigma 18-250mm and Sony 18-55mm with flash in the house. My purpose was to see if the Tamron 28-200mm would serve as an indoor camera for Christmas etc. What a shock when I looked at the pictures. The ones from my old lenses were great. The pictures taken with the new lens were almost totally black. I did some resets etc., but nothing worked. A friend suggested I post my problem on the DP Review forum. Within an hour, a member suggested I change the flash mode from ADI to Pre flash TTL. I did and the flash pictures are now excellent. Apparently some lenses only have five contact points and TTL mode must be used. Sony lenses and some others have eight contact points.

Optically, this lens seems to at least the quality of my other lenses. I don't pixel peep but I did take several shots at various focal lengths and briefly compared them to similar pictures I had taken with my other lenses. To my eye, they are equal in image quality. I take a lot of zoom pictures with my other lenses at 250mm so I was anxious to see if the 200mm shots from this Tamron still looked good after heavy cropping. They do. This is a quality lens.

My first real test of the lens came on a trip to the Orange County, CA, Zoo, a challenging place to take pictures, due to the lighting and the various forms of fencing around the animals. This was my third trip to this Zoo, the first two using other heavier zoom lenses. I received several comments that the pictures I got with the Tamron 28-200 were my best yet. I am totally pleased.

As I understand it, this is an older version of the 28-200mm lens. In fact, the name Sony does not appear on the Tamron box. I must say, however, that it seems to be an ideal lens for the small a55. I can honestly recommend this lens. The price is right and the quality is there.
