Tamron is set to announce a new 17-35mm f/2.8-4 Di OSD lens for full frame cameras. The variable aperture should keep the price down against competition.
Optimum image quality coupled with maximum portability
The 17-35mm F/ 2.8-4 Di OSD (Model A037) is an ultra-wide-angle lens featuring superb image quality integrated into a compact, lightweight body. The use of specialized glass materials enables comprehensive control of the axial chromatic aberrations conspicuous in ultra-wide-angle lenses. The Model A037 offers a high level of sharpness and contrast comparable to the very best of lenses. From the 35mm standard wide-angle for user-friendly snapshot photography, to the ultra-wide-angle 17mm used for professional landscape photography, this lens can meet a wide variety of your needs and yet still offer amazing portability being only 90mm (3.5 in) in length, 83.6mm in diameter, and just 460g (16.2 oz) in weight. With a Minimum Object Distance (MOD) of only 0.28m (11 in), opening the aperture while approaching the subject lets you blur the background. Wide enough to encompass the entire landscape, the Model A037 lets you capture the thrill of the moment in each and every image you shoot.
Backlighting control enables new forms of expression
As strong light sources can often penetrate the lens, wide-angle lenses in particular are made to resolve backlighting issues. The Model A037 has gone through repeated comprehensive ghosting analysis simulation during the development stage. The optical structure performance level has also been maximized. The BBAR (Broad-Band Anti-Reflection) Coating is applied for highly effective anti-reflection and ghosting and flare are brought under control.
AF to capture the moment
The AF drive employs a newly developed OSD (Optimized Silent Drive) to ensure silent operation. Upgraded and optimized for even further reduction in drive noise, this drive allows the lens to be used to your heart’s content in all situations where silence is required. With its greatly enhanced quality and speed, the new outstanding AF performance and tracking capabilities mean you never have to worry about missing a shot even when focusing on moving subjects.
Protect your lens with Fluorine Coating and Moisture-Resistant Construction
The front surface of the lens element is coated with a protective fluorine compound that is water- and oil-repellant. The lens surface is easier to wipe clean and is less vulnerable to the damaging effects of dirt, dust, moisture and fingerprints. Leak-proof seals throughout the lens barrel further protect your equipment, especially when shooting outdoors.
