With the advent of the latest 15x zoom lens from Tamron, the pioneer of high power zoom lenses, the high power zoom lens has steadily evolved from a 7.1x zoom to the world's largest zoom ratio of 15x by combining advanced high power zoom design technologies accumulated by Tamron since 1992. The lens covers an angle of view equivalent to that of a 28mm wide-angle to a 419mm ultra telephoto with just one lens, letting the user capture once-in-the-lifetime images of panoramic landscape images or close-up pictures of children smiling, without having to get too close to the subject and without having to change lenses.
Tamron Di-II lenses are engineered expressly for digital SLR cameras with image sensors commonly referred to as APS-C, measuring approximately 24mm x 16mm. Rendering an ideal image circle for APS-C sensors, Di-II lenses also include properties to optimize
It is a 15x high power zoom lens designed exclusively for digital SLR cameras using the more compact (APS-C) digital size image sensors. The focal length of this lens is equivalent to approx. 28-419mm in 35mm format. Designed as an "all-in-one" lens, it will meet almost all photographic opportunities without changing lenses. The addition of PZD (Piezo Drive) ultrasonic autofocus motor helps make this lens lighter, shorter and slimmer than any previous lens in this category, and provides faster, quieter auto-focusing. The VC (Vibration Compensation) mechanism allows the use of shutter speeds that are much slower than otherwise possible, with no perceptible increase in image blur. It automatically detects movement of the camera and compensates for camera shake when shooting a moving object. This feature is a must in a lens with this longer range of focal length. This lens will focus down to 19.3" throughout the zoom range. This lens is designed exclusively for DSLR cameras with smaller-size sensors.
