Product Description

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.

I have an older version of this lens for my Nikon and always got good results with it. I am using this on a Canon 5D Mk2, believe it or not, and it is great so far. Some barrel distortion that really shows in building shots, etc, but there is good software that can correct that easily. Also, it will be less on non-full frame cameras. Otherwise I think this is one of the best value lenses out there. Probably the ideal travel lens due to it's size, too. It's very small. Maybe the smallest zoom lens of that length. It's also very well made. Mostly metal. I trued out the Canon equivalent and have to say this lens seems sharper and with better color.

The lense met my expectations. If anybody thinks it is a macro lense, it is not. Execept that deceptive tactic on the features, it is a wonderful lense. I have taken 1000s of shots. Best on a tripod and out doors. I prefer my Cannon lense better in the performance and quality. Hey,..but what do you expect for the price?...It was a best buy for me. Zooming is good as expected. Wish it had image stabilisation feature. I still use it and recommends to any one on a limited budget.
