Early last month,\u00a0Tamron\u00a0<\/strong>announced\u00a0\u00a0the development of a second-generation 70-180mm f\/2.8 telezoom for Sony E-mount.\u00a0Today the company\u00a0\u00a0revealed\u00a0new details about this lens, including a release date and price.<\/p>\n

The new fast zoom lens has received many improvements, including Tamron’s proprietary Vibration Compensation (VC) mechanism, which, however, does not make the lens much larger: it weighs only 855 grams and is 156.5 millimeters long.<\/p>\n

\nTamron 70-180mm F2.8 Di III VC VXD G2<\/p>\n

The first version, which lacks optical image stabilization, is slightly lighter and shorter: 811 g and 149 mm.<\/p>\n

Thanks to stabilization, the new lens will allow you to take significantly clearer pictures at long shutter speeds.\u00a0Tamron claims its 70-180mm f\/2.8 G2 is\u00a0\u201cthe world’s smallest, lightest full-frame, fast f\/2.8 telezoom lens with stabilization<\/i>\u00a0. \u201d<\/p>\n

While VC is perhaps the most notable new feature in the second-generation telezoom lenses, Tamron has changed the optical design.\u00a0It now has 20 elements in 15 groups, rather than 19\/14 like its predecessor.<\/p>\n

\u201cThe design has been completely redesigned and includes a more efficient arrangement of special elements, including one XLD (extra-low dispersion), one hybrid aspherical, three LD (low dispersion) and two GM (molded glass aspherical),\u00a0\u201d\u00a0Tamron<\/i>\u00a0explains ‘e, adding that the new optical formula promises better control of chromatic aberrations and delivers higher resolution.\u00a0The lens also features a second-generation broadband anti-reflective coating (BBAR-G2) to reduce ghosting and flare.<\/p>\n

Like the first generation 70-180\/2.8 lens, the new version uses a VXD linear motor focusing mechanism.\u00a0However, Tamron says tracking performance has improved.<\/p>\n

Additionally, the new lens has a shorter minimum focusing distance.\u00a0The G2 can achieve a maximum magnification ratio of 1:2.6 when using autofocus, which is better than its predecessor’s 1:4.6 ratio.<\/p>\n

Of course, the lens is compatible with Tamron Lens Utility.\u00a0The Tamron 70-180mm f\/2.8 Di III VC VXD G2 features a weather-resistant design, a fluorine coating on the front element, and the same front filter thread diameter (67mm) as most other Tamron lenses for E-mount cameras, and supports many features of Sony cameras, including fast hybrid autofocus and eye autofocus.<\/p>\n
