Tamron has announced a new 100-400mm lens that will be available in the next few months. Spanning a versatile range of long focal lengths, this telephoto zoom is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it will provide a 160-640mm equivalent focal length range. Three LD (low dispersion) elements are used in the optical design to greatly reduce chromatic aberrations and color fringing for improved clarity and color accuracy throughout the zoom range. An eBAND coating has been applied to suppress ghosting and lens flare for improved contrast when working in backlit conditions. VC image stabilization helps to minimize the appearance of camera shake for more effective handheld shooting in difficult lighting conditions. An Ultrasonic Silent Drive (USD) autofocus motor delivers quick and precise focusing performance to suit working with moving subjects. This motor also affords full-time manual focus control, and it is possible to focus on subjects as close as 4.9' away. Dual Micro-Processing Unit control system contributes to quick and responsive performance for both the autofocus and Vibration Compensation systems. A sealed, dust- and moisture-resistant construction benefits this lens' use in inclement conditions, and a fluorine coating has also been applied to the front lens element to protect against dust, dirt, and smearing. Through the use of magnesium alloy components, the lens's physical design is both lightweight and durable. An optional removable rotating tripod collar is available, which features an Arca-type compatible foot and benefits working with the lens atop a tripod or monopod. Supports working with the optional Teleconverter 1.4x to further extend the effective focal length range to 140-560mm. Compatible with optional TAP-in Console for fine-tuning select focusing adjustments and for updating lens firmware. For more info, please visit B&H Photo.
