Tamron 28-300 VCLooks like Tamron is jumping on the super-zoom image stabilized band wagon the new Tamron 28-300 f/3.5-6.3 XR Di VC lens that was announced today. Bob Atkins has a handy preview article. You can also check out the features in the press release below.


Mr. Morio Ono, President of Tamron Co., Ltd., has announced the successful development of the AF28-300mm F/3.5-6.3 XR Di VC LD Aspherical (IF) MACRO zoom lens, a high power zoom lens designed for SLR cameras with full-size format(Model A20), now equipped with a Vibration Compensation (VC) mechanism. The AF28-300mm F/3.5-6.3 XR Di VC is the ultimate high power zoom lens that covers everything from wide-angle to telephoto and macro. Tamron has incorporated a Vibration Compensator, an anti-shake mechanism developed by Tamron, into the highly versatile zoom lens. The new AF28-300mm F/3.5-6.3 XR Di VC LD Aspherical (IF) MACRO zoom lens offers the convenience, comfort and versatility of a high power zoom lens and the capability to reduce hand-shake blur on SLR cameras using either APS-C size or full size format imagers.

When the AF28-300mm F/3.5-6.3 XR Di VC is used with a full size format SLR camera, it covers the tremendous focal length range from 28mm in wide angle to 300mm ultra telephoto. When mounted on a DSLR with an APS-C sized imager, the lens covers a 43mm wide angle to 465mm equivalent ultra telephoto* (full size format equivalent, in a diagonal angle of view of 5°20′).

(*) The ratio Tamron uses to convert from full size format to APS-C focal length is 1.55X.


1. VC (Vibration Compensation) Mechanism Reduces Hand-shake

The proprietary VC (Vibration Compensation) mechanism developed by Tamron features a triaxial configuration using three pairs of driving coils and slide balls around the compensator group of the lens’ optical system. Since the compensator lenses are supported with rolling friction of the balls, the response performance is enhanced and the construction is simple, which results in the compactness of the lens. The lens incorporate a highly accurate gyro sensor for detecting hand-shake, which, combined with a 32-bit RISC CPU, offers comfortable anti-vibration effects.

2. Outstanding Design Realizing High Zoom Power, VC Mechanism and Compactness

The AF28-300mm F/3.5-6.5 XR Di VC integrates optical technologies that Tamron has accumulated as the pioneer and leader of high power zoom lenses in order to realize the desired compactness even while incorporating the VC mechanism. The optical system uses a number of lens elements made from special optical glass materials including XR (high refraction index) glass elements, GM (glass-molded aspherical lens) elements, hybrid aspherical elements, LD (low dispersion) glass elements to compensate for on-axis and lateral chromatic aberrations and AD (anomalous dispersion) glass element. The lens offers high contrast, high resolution performance and flatness of the image field as a one-does-it-all zoom lens designed to match the characteristics of DSLR cameras.

3. Revolutionary MFD of 0.49m (19.3″) throughout the Zoom Range Provides 1:3 Macro Magnification Ratio

The AF28-300mm F/3.5-6.3 XR Di VC LD MACRO boasts an MFD (minimum focusing distance) of 0.49m (19.3″) over the entire zoom range, a top-class closing focusing capability among high power zoom lenses for full-size format SLR cameras, which provides the remarkable maximum macro magnification ratio of 1:3 at the 300mm telephoto end.

4. Internal Surface Coatings Minimize Ghosting and Flare

Through the use of “Internal Surface Coatings” (i.e., multiple-layer coatings on cemented surfaces of plural elements) and multiple-layer coatings to prevent reflections from lens surfaces, ghosting and flare due to reflections that occur when light enters through the front element as well as reflections caused by the imager itself in the mirror box are reduced to the absolute minimum.

5. Ultra-high Zoom Power, yet Lightweight and Compact Design Thanks to New Mechanical Devices

Tamron has reviewed the roles that respective barrel parts play in order to achieve the high power, compactness and light weight. As a result, dimensional increases are confined to a mere 17.8mm (0.7″) in overall length and about 5mm(0.2″) in diameter, when compared with the existing AF28-300mm (Model A061), despite the incorporation of the VC mechanism.

6. Zoom Lock Mechanism for Enhanced Portability

The zoom lock prevents unwanted barrel extension when carrying the lens/camera combination over the shoulder.

7. Flower-shaped Lens Hood

A flower-shaped lens hood is included as a standard accessory. The special hood provides optimum shading of superfluous light rays that enter from the rectangular frame outside the image field.

Have you had any problems with your Tamron 28-300 VC lens? I’m on my second one and it is beginning to exhibit the same problem as the first lens (using it with both a Nikon D200 and D3). The problem starts with the lens hitting a stop point at 80 mm when zooming from long focal length (>80 mm) to short focal length (< 80 mm). I can get past this stopping point by forcing the lens through the 80 mm point quickly. Each time I do this there is a clicking sound as if the lens mechanism is having to jump over something inside. The catch does not occur in the opposite direction. Tamron took nearly two months to repair the first one, and when it was returned the zoom mechanism was fixed but it would not autofocus. They quickly replaced the first lens with a new second lens, but now the second lens has developed the same sticking point in the zoom mechanism. I’m not hard on my equipment and consider the use it has received in the two months I’ve had the replacement lens to be light. Have you experienced similar problems or do you know of anyone with similar problems? I’m getting tired of sending this lens back for repairs. I bought the first one just 10 months ago. Other than these operational problems, the lens performs well for the purposes it was purchased. Thanks for any help you can send my way.
