Product Description

From the Manufacturer

The new 28-200 Super Zoom lens from Tamron. Developed because we believe a 28-200 zoom should be compact and lightweight enough to carry anywhere. Versatility that lets you capture all of your holiday and everyday snapshots. High image quality to give you the optical results that make your photographs colorful and sharp. So fun that you’ll want to take your camera with you all of the time.

Soft, natural tones for superior image quality.
This lens achieves delicate, beautiful image quality with a natural depth of expression. The optical configuration employs seven aperture blades for superior picture results.

Better close-ups.
The Tamron 28-200mm provides a remarkable 19.3" minimum focusing distance throughout the entire zoom range, and a macro magnification of 1:4 at 200mm. For example, you can shoot an object about the size of a postcard and fill the frame completely.

Features

• 25% More Compact than previous model
• Extremely Lightweight only 12.5 ounces
• Very Compact just 3 inches long
• Small 62mm Filter Size

XR Technology
XR (Extra Refractive Index) glass is effective in reducing the optical length of the lens through refractivity. The optical configurations of the new 28-200 and 28-300 (models A03 and A06) incorporate innovative new XR glass elements, improving overall optical power distribution, reducing all types of aberrations while making for unprecedented compact packages.

With a short barrel, it is possible to obtain the same visibility (aperture value) as with a long barrel. By using this principle, we were able to shorten the optic system length for a more compact overall lens design while maintaining aperture values.

The XR lenses allow for a smaller lens diameter while maintaining the same aperture values as our previous lenses.

LD (Low Dispersion) Glass
Chromatic aberration is a form of optical noise that reduces the sharpness of an image. LD elements are made from special glass materials with extremely low dispersion indices (characteristics that separate or refract a ray of light into rainbow colors) that effectively compensate for chromatic aberration that is a particular problem at ultra telephoto of 300mm or more.

Internal Focusing
Aside from enhancing lens maneuverability, Tamron’s Internal Focusing System provides additional benefits. Chief among them is a reduced M.O.D. throughout the entire focal range on both lenses (19.3"). Additionally, it improves optical characteristics by minimizing illumination loss at image corners and suppresses aberrations that are caused by focusing positions. Another benefit of IF is a stationary front element making the use of polarizing and other special effects filters easy.

Zoom Lock
Convenient Zoom Lock prevents mishaps. The zoom lock mechanism prevents the lens from extending downward under its own weight when carrying. The feature locks the zoom ring of either lens in the 28mm position to secure the lens at its shortest position for trouble-free portability.

Aspherical Design
The Aspherical Lens technology compensates for spherical aberration to achieve outstanding image quality. At the same time, Aspherics reduces the number of elements needed resulting in a more compact, lightweight lens package.

AD(Anomalous Dispersion)Glass
AD glass is a special optical glass that delivers an abnormally large partial dispersion ratio (amount of dispersion at a given wavelength range within visible light) relative to a specific wavelength zone. By combining AD glass elements with elements made of normal glass with different dispersion characteristics, dispersion factors of a specific wavelength can be controlled, resulting in effective compensation of on-axis chromatic aberration on telephoto lenses, or lateral chromatic aberration often associated with wideangle lenses of conventional optical configuration.

Product Description

Tamron offers the world's smallest, most lightweight 28-200mm high-magnification zoom lens. With a minimum focal distance over the entire zoom area of 49cm, and a maximum magnification of 1: 4 (at 200mm), this remarkable lens achieves high-magnification zoom performance with the compact size of a standard zoom lens. Through XR (Extra Refractive Index) glass and efficient use of aspherical lenses, Tamron has achieved a 25% reduction in size and a 27% reduction in weight over the previous model (model 371D), along with a decrease in filter diameter by two-steps ?72mm- ?62mm without compromising the superior image quality characteristic of Tamron 28-200 lenses.

5.0 out of 5 stars Great versatile lens, March 16, 2002

By A Customer

You cannot go wrong with this new lens by Tamron! I bought this lens about a month ago for use with my Nikon N65 and am very pleased. The quality of pictures this lens takes is better than my Nikor 28-80 lens plus I don't have to switch between that lens and my 80-200 lens! Picture quality and contrast is superior throughout the range of this lens (no distortion) and the zoom ring operates very smoothly. I've also noticed better depth of field in this lens over my two other lenses.

I've used the lens mainly for sporting/outdoor events (bright sun and overcast conditions) but have also taken pictures indoors in various lighting situations with the same great results. So far, I've taken about 12 rolls of film (mostly 800 speed) and have been very satisfied with my pictures. No color correction by my lab has been necessary and my developer always brags about my pictures! Between the Nikon camera and this Tamron lens, you can't go wrong!

The lens is lightweight (12 oz) but don't think you are exchanging quality for a lighter lens. This newest generation lens by Tamron combines the best of both worlds. Having to buy 62 mm filters for this lens vs. the 72 mm filters that most 28-200 zoom lenses require is another bonus.

If you are thinking about getting a 28-200 zoom lens, I definitely recommend this lens!
