Tamron 70-210mm F/4 Di VC USD for Canon EF Digital SLR Camera (Renewed)

Product Description

High–performance telephoto zoom lens with a constant F/4 aperture Leveraging Tamron's years of knowhow developing telephoto zoom lenses, Model A034 achieves superb optical performance with high contrast and resolution. The optical construction (20 elements in 14 groups) uses three LD (Low Dispersion) lens elements to effectively compensate for axial and transverse chromatic aberrations, thereby ensuring crisp and crystal–clear image quality across the entire frame. Furthermore, Model A034 features a constant maximum aperture of F/4 throughout the entire zoom range, thus providing superior control over depth–of–field and excellent bokeh. Compared to large aperture telephoto zoom lenses, the new A034 is lighter with a weight of just 30.3 oz. and is more compact with a total length of only 6.8 in. for excellent portability. The lighter weight and smaller size make this new lens easier to carry and instantly spring into action. Class–leading magnification ratio and MOD (Minimum Object Distance) Model A034 boasts the highest–in–class maximum magnification ratio of 1:3.1 and the shortest–in–class* MOD of 37.4 in. The shorter working distance enables photographers to capture close–up images of small objects like flowers while using a telephoto zoom. *Among 70–200mm F/4 class interchangeable lenses for full–frame DSLR cameras (as of January 2018: Tamron) Highly reliable internal zoom mechanism Thanks to an internal zoom mechanism, the physical length of the A034 does not change during zooming, thereby minimizing changes in the center of gravity and providing more stable use and operation. In addition, it's not necessary for the photographer to move backwards even when shooting space is limited, for instance, when photographing through a wire mesh fence at a zoo. So–called "zoom creep" is impossible because the overall length never extends.
