Maintaining the high performance of the previous model, Tamron's new 28-300mm zoom lens now features our "Di" design, making it the ideal lens for use with both digital and film cameras. The "Di" design is achieved by applying a new optical design to its coated surfaces, and by further enhancing our already stringent quality control system. Whether you shoot film or digital, the lens provides high image quality for both platforms. When used with APS-C size digital SLR cameras, the lens provides an angle of view equivalent to approximately 44-465mm, covering the standard to ultra telephoto range with no sacrifice of quality or aperture range.
