Tamron will start shipping itsstarting on January 17 in the US for a price of $1,069, the company said Sunday.
That's not too much higher than the company's $950 AF 200-500mm f/5.0-6.3 Di LD SP lens, which has a more restricted zoom range but no image stabilization. However, greater zoom ranges often come with optical compromises such as worse sharpness, distortion, and chromatic aberration.
The new supertelephoto has a flexible zoom range, though its aperture range of f5 at 150mm to f6.3 at 600mm means it's not as fast as premium professional supertele models. It's geared for wildlife and sports photographers and is relatively affordable, compact, and light.
The lens, announced in November, has 20 lens elements and new coatings designed to cut down flare and ghosting. It weighs 1951g (68.8oz) and is 257.8mm (10.1 inches) long. Its Vibration Compensation (VC) technology is designed to counteract camera shake. It's got a nine-blade circular diaphragm to improve the look of out-of-focus areas, and its close-focus distance is 2.7m (106.3 inches).
Tamron will offer versions for Canon, Nikon, and Sony SLR cameras.
