Tamron announced today it's brought vibration compensation to two full-frame lenses, the 70-200mm F/2.8 Di VC USD telephoto and the SP 90mm F/2.8 Di VC USD macro.
Both of the lenses will ship by the end of the year for Canon, Nikon, and Sony cameras, Tamron said just ahead of the Photokina 2012 show, a major camera event held every two years in Germany. The company didn't disclose prices.
Vibration compensation -- known as vibration reduction at Nikon and image stabilization at Canon -- shifts a lens element to counteract camera shake. It can dramatically cut down on blurry shots, especially with longer lenses or slower shutter speeds. But wide apertures still have a role: image stabilization won't help freeze the action of twitchy birds or sprinting soccer players, and wide apertures also provide a pleasingly out-of-focus background that's very desirable for portraits.
The two lenses fit nicely into one of the Photokina trends: a surge in full-frame cameras. Those are models whose image sensor is the size of a full frame of 35mm film. That's a costly option, and it generally makes cameras and lenses bulkier and heavier, but the larger sensors provide better image quality, especially in dim light.
, cheapest full-frame SLR on the market. And the marries a full-frame sensor to the company's transparent mirror technology. This approach skips the flip-up mirror of a single-lens reflex camera and instead uses a fixed mirror and electronic viewfinder.
Tamron's new 70-200mm lens has 23 lens elements, including one extra-low dispersion element and four low-dispersion elements to cut down on chromatic aberration. It weighs 51.9 oz (1,470g), is 7.4 inches (188mm) long, has nine aperture blades, and has a close-focus distance of 51.9 inches (1.3m).
The 90mm macro lens can reproduce subjects at 1:1 scale in close-up shooting. It's got a close-focus distance of 11.8 inches (0.3m), weighs 19.4 oz. (550g), and among its 14 elements are two extra-low dispersion elements and one low-dispersion element.
