Tamron press release:
Tamron releases the smallest, lightest ultra-wide-angle zoom lens in its class
A sophisticated balance of outstanding optics and matchless mobility
17-35mm F/2.8-4 Di OSD (Model A037)
August 6, 2018, Saitama, Japan–Tamron Co., Ltd. (President & CEO: Shiro Ajisaka), a leading manufacturer of optics for diverse applications, announces the launch of a new ultra-wide-angle zoom lens, the 17-35mm F/2.8-4 Di OSD (Model A037), for 35mm full-frame DSLR cameras.
The vision behind the Model A037 is that of an ultra-wide-angle zoom lens, which has a separate concept from SP 15-30mm F/2.8 Di VC USD (Model A012), with superb image quality and easy portability. At just 90mm (3.5 in) in length and 460g (16.2 oz) in weight, it is the smallest and lightest in its class. The focal length ranges from an ultra-wide 17mm that is suitable for professional landscape photography to a standard 35mm good for snapshot photography. As for F-stops, the wide-angle end is a large aperture F/2.8, and at the telephoto end is a fast F/4. The Moisture-Resistant Construction and Fluorine Coating, help to enhance the user’s photographic experience. For those looking to try out an ultra-wide-angle zoom lens for the first time, as well as having a lens that is easily portable, the A037 is the definitive choice.

1. High-performance imaging for shooting vast landscapes in sharp detail
The optical construction (15 elements in 10 groups) uses four LD (Low Dispersion) lens elements to minimize axial chromatic aberrations that can occur with ultra-wide-angle zoom lenses. With two properly positioned GM (Glass Molded Aspherical) lenses, distortion and other aberration can be satisfactorily corrected as well. Being the smallest and lightest in its class* and dedicated to high quality imaging, the engineers have paid particular attention to size. The lens has also been carefully designed to allow peripheral point image reproducibility and thereby facilitate a high degree of sharpness and contrast.
The Minimum Object Distance (MOD) for the entire zoom range is a short 0.28m (11 in), so background blurring is still possible when opening the aperture and approaching the subject close-up with this ultra-wide-angle zoom.
