Tamron 28-300mm XR Di f 3.5-6.3 Macro Canon Mount

Tamron 28-300mm XR Di f 3.5-6.3 (IF) Macro Canon Mount

Tamron is the leader in developing high-ratio zoom lenses for everyday use, releasing the first-generation 28-200mm zoom in 1992 and reinforcing the value of high-magnification zoom lenses with subsequent releases. With a key strategy of building high ratio zoom lenses to exceed user expectations, Tamron has developed several generations of the 28-200. More recently Tamron extended the telephoto range to 300mm in the AF28-300mm Ultra Zoom XR F/3.5-6.3 LD AD Aspherical [IF] Macro, which this lens replaces. In the process, they have garnered more than 22 internationally prestigious awards for products in this category. The latest versions of these lenses offer the user a combination of features long desired by photography enthusiasts and newcomers to SLR photography:

* compact size and light weight
* extended focal length range
* smaller filter size
* outstanding optical performance
* improved mechanical construction.

Special features and characteristics

One of the world's most compact, lightweight lenses in its class
This lens provides superior convenience in handling in a highly compact design. The front filter fitting is only 62mm, the maximum diameter just 73mm, the length 83.7mm, and the weight a remarkable 420 grams.

XR technology
Despite the remarkable reduction in size, Tamron 28-300 XR Di provides outstanding optical quality through an improved optical system employing XR (Extra Refractive Index) glass and complex aspherical elements.

Real close-up capability
Amazing macro capabilities are available with a minimum focusing distance of a mere 49cm over the entire zoom range, and a maximum magnification ratio of 1:2.9 at 300mm. This allows the photographer to fill the frame with objects of 10.5 x 7cm in size, or about the size of a music cassette.

Improved zoom torque
Through the incorporation of new mechanical designs such as a Moving Triple Cam, the lens zooms smoothly and consistently from wide angle to telephoto.

Nine-blade diaphragm
The 9-blade diaphragm design provides a soft blurred background that is very pleasing in portraiture and macro photography, isolating the subject from a distracting background and providing a professional-looking image. This blurred effect is enhanced at high magnification and/or open aperture settings, for softer, more natural images.

Zoom lock mechanism
The Zoom Lock prevents unwanted barrel extension when carrying the lens/camera combination. The user simple retracts the lens to the 28mm position and locks the barrel in place. This eliminates the danger of accidentally knocking the lens while walking around.

Flower-shaped lens hood
A glare-reducing flower-shaped lens hood is included as a standard accessory. Tamron was the first manufacturer to use the specially cut hood to provide optimum shading from superfluous light rays entering the rectangular frame from outside the picture angle. From 28mm wide angle to 300mm telephoto, the flower-shaped lens hood allows for sharp and clear image quality free from glare.

High image quality by virtue of "Di" (Digitally integrated) design
The "Di" design is achieved by applying a new optical design to its coated surfaces, in order to reduce the ghosting and flare caused by aberrations, and by further enhancing our already stringent quality control system. The new AF28-300mm Di is reborn as a high power zoom lens now ideal for use with interchangeable-lens digital cameras as well as film cameras.

Offers the same convenience and compactness
The amazing changes in angles of view from a 10.7X zoom lens open up completely new horizons, especially when combined with the fundamental attraction of digital SLR cameras: the ability to confirm on the spot the quality or composition of captured images. The new AF28-300mm Di offers the same compactness as that of the previous model designed primarily for film cameras.

Ideal for both digital and film SLRs
The new AF28-300mm Di can be used with both digital SLR cameras and conventional 35mm AF-SLR film cameras. It provides an impressive angle of view equivalent of 42-450mm ultra telephoto when used with a Nikon digital camera, and provides a 28mm wideangle on a 35mm film SLR.
