Product Description

Color Name: Nikon

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

Product OverviewThe 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.

This review is from: Tamron Autofocus 28-200mm f/3.8-5.6 XR Aspherical (IF) Lens for Canon SLR Cameras (Black) (Electronics)

If you are the adventure type holiday fotographer, this is the lens you need. Much better then it's predecessors in optical quality and weight. I got triggered to buy one, because it won the joint European Foto Magazines prize of 'lens of the year'.

When you like to travel light, this is the only lens you need.

Watch out, that you get the right lens, because there are 5 different Tamron 28-200 predecessing models around.

This review is from: Tamron Autofocus 28-200mm f/3.8-5.6 XR Aspherical (IF) Lens for Canon SLR Cameras (Silver) (Electronics)

I have been using the black intl' version of this lens or some time now (I think) and I have been quite happy with it, except that that if you like using Canon's the direction you have to twist your hand to zoom is the OTHER WAY as with Canon! It's a small annoyance, but yes it will get you frustrated if you turn the lens one way to zoom but start pulling back!

The zoom is slow compared to the new USM's from canon, and it seeks a lot. At the far end of the lens spectrum (about 130-200mm) the lens gets really dark and the picture quality degrades, and since the lens gets longer every little vibration in your body gets exaggerated if you are using a long exposure (on a canon 10D around 1/30 or longer).

This is a solid buy but honestly I think that if you can afford the extra cost invest in a Canon lens.

3.0 out of 5 stars Got a "pretty good" one on the second try. Poor quality control, October 1, 2006

This review is from: Tamron Autofocus 28-200mm f/3.8-5.6 XR Aspherical (IF) Lens for Canon SLR Cameras (Black) (Electronics)

I recently bought a Canon EOS Rebel XT digital SLR, intending to use some Sigma lenses I had for my old EOS 630, and was disappointed to find they wouldn't work on the Rebel and couldn't be upgraded. I picked up a couple of used Canon lenses which covered the range I needed, but still missed the versatility of my old Sigma 28-200mm.

I have had good luck with Tamron lenses in the past, and the reviews looked good, so I bought a new Tamron 28-200mm f/3.8-5.6 XR lens, thinking it would be an equivalent replacement for the old Sigma.

The first tryout of the lens was extremely disappointing. The first images shot in the back yard were soft, edge definition was fuzzy, and contrast was muddy. To give the lens a second chance, I took it out for a nature photo session, running the gamut from macro shots of flowers to landscapes, over the full range of f/stops and zoom positions. Again, the images were poor, exhibiting chromatic aberration, flare, and coma, with no improvement with reduced f/stops. I hadn't seen a lens this bad since a Vivitar 180mm telephoto I had in the 1970's.

Thinking that no one would intentionally manufacture a lens this poor, I returned it as defective, for exchange for another. The replacement arrived, and its performance confirmed that the first one was defective.

While the replacement lens performs acceptably, it isn't up to the quality level of my old Sigma 28-200, or the Canon 35-135mm zoom I recently bought used (but it probably is as good as the 18-55mm zoom that came with the Rebel XT). It exhibits some softness at object edges, but improves at smaller apertures. I'm impressed with the lack of flare, even with no hood and shooting toward a bright overcast sky. After some moderate sharpening in Photoshop most images are pretty good.

So my conclusion from all this is:

There's apparently some quality control issues with Tamron's Chinese assembly facility. If you buy one and it performs poorly, try another before giving up on it.

The lens I finally got is "pretty good" but not terrific. It's adequate for casual use, but I'm keeping the Canon zoom, and saving up for a Canon macro lens for the serious stuff.

The MSR price for this lens is ridiculous, and the "street price" is kind of high for what you get.

I'd buy Tamron again, but not without there being a return policy from the seller.
