Tamron's eBAND Coating and BBAR (Broad-Band Anti-Reflection) Coating help suppress flare and ghosting for class-leading image quality. New eBAND (Extended Bandwidth & Angular-Dependency) Coating This new coating technique developed by Tamron deploys a nano-structured layer (1nm = 1/1,000,000mm) of ultra-low refractive index, with dimensions smaller than the wavelengths of visible rays of light. This nano-structured layer coupled with the sophisticated multiple layer coatings underneath, yiel

Tamron has announced the development of a 150-600mm F5-6.3 zoom lens for full-frame and APS-C sensor cameras. It will feature 20 elements in 13 groups and have a minimum focus distance of 2.7m. Tamron will also include VC (Vibration Compensation) image stabilization and USD (Ultrasonic Silent Drive) technologies. The lens will be developed for Canon, Nikon, and Sony mounts. Pricing and availability are still to be announced.

That dream has long since become a reality, but for some, the dream wasn't big enough. They've been asking for an altogether different -- yet still affordable -- camera. They needed it to have a bigger sensor, and to drop the bulky mirror box of an SLR. Until now, they could choose one or the other. Sony has changed all that, with the launch of the full-frame Sony A7 and A7R mirrorless cameras. The two cameras are very closely-related, and in this first impressions review, we
