Tamron Working On 70-200mm F/2.8 DI VC USD Telephoto Zoom Lens
The Tamron 24-70mm F/2.8 VC gets a bigger playmate
Recently, Tamron was the first lensmaker out of the gate to slug Vibration Compensation (their name for image stabilization) into a 24-70mm F/2.8 standard zoom lens. The results were pretty impressive, but now they’ve moved on to another classic zoom range in the 70-200mm F/2.8 DI VC USD.
Expected to ship by the end of 2012, the new 70-200mm lens is expected to be more compact than existing F/2.8 versions from various companies. it will be 7.7 inches long in total, weigh roughly 52-ounces (3.25 pounds) and use a 77 millimeter filter.
The elements will include one piece of Extra Low Dispersion and four pieces of Extra Low Dispersion glass. It will also use Tamron’s multi-layer coatings to reduce effects like ghosting and distortion.
The Vibration Compensation system has moved away from the moving magnet system and gone to a moving coil system, which contributes to the reduction in overall size and weight. It uses a nine-blade rounded diaphragm in a further effort to smooth out out of focus areas.
It will be driven by an Ultra-Silent Motor (USM), have a total of 23 elements in 17 groups and stop all the way down to F/32.
Hopefully we’ll get a chance to get our hands on an early model next week at Photokina 2012.
