Tamron today launched the Tamron 70-210m f/4 Di VC USD, a compact zoom lens for full-frame Nikon and Canon DSLRs. Featuring a best-in-class 1:3.1 maximum magnification, the lens has internal zoom dual Microprocessing Unit design for high-speed and accurate AF performance, as well as powerful VC (Vibration Compensation). Tamron also announced that it is developing a 28-75mm f/2.8 premium lens for Sony full-frame mirrorless cameras.
Tamron 70-210mm f/4 Di VC USD Lens
The Tamron 70-210mm F/4 Di VC USD (Model A034) is a compact telephoto zoom lens for full-frame Nikon and Canon DSLR cameras. It is said to provide superb optical performance throughout the entire zoom range and features a maximum magnification ratio of 1:3.1, the highest in its class. The design includes an internal zoom mechanism that provides solid mechanical construction and stable, reliable operation.The lens also employs a Dual MPU (Micro-Processing Unit) design, which enables high-speed and high-accuracy AF performance as well as powerful VC (Vibration Compensation) image stabilization for flexible and versatile use in various situations. It has Fluorine Coating for its front element, and Moisture-Resistant Construction.
The optical construction (20 elements in 14 groups) uses three LD (Low Dispersion) lens elements to effectively compensate for axial and transverse chromatic aberrations.The lens has a constant maximum aperture of F/4 throughout the entire zoom range for control over depth-of-field and excellent bokeh. It weighs 30.3 oz. and is more compact with a total length of 6.8 in. The lens is sealed against moisture, making it a good all-weather lens.
Tamron claims the internal zoom mechanism is highly reliable; since the lens’s physical length doesn’t change during zooming, the center of gravity remains constant to provide more stable handheld operation, and zoom creep is eliminated. The front element does not rotate—a boon for polarizing filter users. The company claims high performance focusing and vibration reduction.
The lens is compatible with the optional TAMRON TAP-in Console, an optional accessory product that provides a USB connection to a personal computer, enabling users to easily update a lens’s firmware as well as customize features including fine adjustments to the AF and VC. An electromagnetic diaphragm system, which has been a standard feature for Canon-mount lenses, is now employed in Nikon-mount lenses. More precise diaphragm and aperture control is possible because the diaphragm blades are driven and controlled by a built-in motor through electronic pulse signals.
The Tamron 70-210mm f/4 Di VC USD will be available in Canon and Nikon mounts from Adorama for $799. It can be pre-ordered now; it is expected to ship in April.
Tamron 28-57mm f/2.8 Di III RXD
Tamron also teased that it is developing a new mid-range zoom for Sony mirrorless cameras, the 28-57mm f/2.8 Di III RXD. Features include minimum focus of 7.5 inches, a new AF driving system that is said to be remarkably quiet, and moisture-resistant construction. A Direct Manual Focus feature will allow Sony cameras to instantly switch between AF and manual focus.
