Features:

Camera shake can ruin your photos, particularly at telephoto or in low light. Tamron's state-of-the-art Vibration Compensation mechanism incorporated into the award-winning 28-300mm zoom gives you blur-free hand-held images for incredible results! Finally, the technology you need in the lens you want.

Working with tripods or other camera supports helps achieve sharp shots, but can slow you down.That’s where Tamron’sVibration Compensation technology can make a big difference in the quality of the images you capture, allowing you to get crystal-clear exposures when handholding your camera.

Tamron’s newAF28-300mm ƒ/3.5-6.3 XR Di VC LD Aspherical (IF) Macro Zoom lens gets you close to the action, with a phenomenal 10.7x range, from wide-angle to powerful telephoto. This versatility makes the lens ready for practically any photo opportunity, from indoor portraiture to sports action and travel scenics.

The most exciting feature of the lens is Tamron’s Vibration Compensation mechanism. Triggered by a gyro sensor that detects unintentional camera movement caused by handholding your camera, the system automatically shifts special optical elements in the lens to counteract the movement, resulting in crisp, sharp shots.

Another outstanding feature of the Tamron AF28-300mm is its Macro capability, providing a 1:3 magnification ratio at 300mm and a minimum focusing distance of 19.3 inches throughout the entire zoom range.Whether shooting wide to capture more of the subject’s surroundings or at full zoom, you’ll get remarkable details and close-up perspective.

To further enhance ease of use and spontaneity, the lens features a lightweight, compact design, the result of Tamron’s efforts to re-examine lens barrel construction.

The dimensions of the new AF28-300mm are just 0.7 inches longer and 0.2 inches larger in diameter than the previous 28-300mm zoom, despite the inclusion of the new Vibration Compensation system.

With the flexibility of the zoom range and the compact design, you’re freed from carrying multiple, larger lenses, which can slow you down when the right moment presents itself.

For the best image quality and light transmission, the AF28-300mm prevents ghosting and flaring with special Internal Surface Coatings that stop stray light from reaching the sensor and dramatically reduce reflections caused by the camera’s imager. The result is truer, better colour and tonality.

The AF28-300mm is compatible with both full-frame and APS-C image sensors. When used with APS-C sensors, the equivalent focal range is approximately 43-465mm, providing ultra-telephoto performance.
