Tamron Announces a Full-Size High-Speed Telephoto with VC and USDTamron boasts that the SP 70-200mm F/2.8 Di VC USD currently in development at the company is the most compact in its class. The lens comes equipped with one Extra Low Dispersion glass element and four Low Dispersion elements, along with a new high-contrast high-resolution optical design. Tamron has also added multi-layer coating to help stop flare and ghosting.
Of course, that's not all there is to the SP 70-200mm F/2.8 Di VC USD. As you might notice from the initials appending the name, the new telephoto offers up Vibration Compensation using a moving coil method. It also packs Tamron's ultrasonic motor to power an autofocus that's both fast and quiet. And, with a fast f/2.8 aperture, you'll be able to produce pleasing bokeh effect, as well as increase your efficiency in low lighting situations.
Tamron's 70-100mm telephoto will be shipping by the end of the year, in Canon, Nikon and Sony mounts. The Sony version will lack image stabilization, since Sony dSLRs offer SteadyShot IS in the body itself. Pricing information yet to be announced.
