Product Description

From the Manufacturer

Introducing the world’s smallest and lightest 28-300mm ever!*
XR, LD, AD, and ASL glass ¾ a virtual alphabet soup of advanced optical designs that make Tamron’s new A06 28-300mm XR the most compact 28-300 zoom available. This new lens offers the user extended telephoto range ideal for such subjects as sports photography, wildlife and landscape. And its superb macro magnification (1:2.9 at 300mm) rounds out the A06’s remarkable functionality for almost every photographic situation. It’s all the lens you need.

1:2.9 Macro - Zoom in on subjects the size of an audio cassette.
The Tamron 28-300mm takes the evolution of zoom technology to the next level by providing a remarkable range that can even take true macro images. The A06 reaches a remarkable 1:2.9 maximum macro magnification at 300mm at 19.3 inches.

The Features

• 28% lighter than previous model
• The lightest available astoundingly light at 14.8 ounces
• More compact than any lens like it just 3.3 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

The 28-300 mm XR (Model A06) zoom achieves a remarkable 25% reduction in size, and 28% reduction in weight compared with the previous 28-300 mm (model 185D) - making the A06 the smallest, lightest 28-300 zoom in existence today. To achieve such compact, lightweight lens design, Tamron further improved upon the Moving Triple Cam technology introduced in the 28-200 XR (Model A03), achieving a solid, stable two-step extension action mechanism to attain the 300 mm zoom setting. XR (extra Refractive Index) glass is effective in reducing the optical length of the lens through high refractivity. LD (Low Dispersion) and AD (Anomalous Dispersion) glass minimize loss of sharpness caused by color blurring at the tele end of the focal range, while ensuring vivid, quality imaging. The ASL lens technology compensates for spherical aberration to achieve outstanding image quality. At the same time, reducing the number of elements results in a more compact, lightweight lens package.

5.0 out of 5 stars Completely Satisfied, June 8, 2004

By	Ron R. (Woodstock, Ga United States) - See all my reviews

I've been using this lens for about 2 months now and I am completely satisfied. I use it for everyday photos, wildlife shots, close ups and anything in between. It delivers crisp photos though out. Remarkable performance and the price can't be beat!
