Tamron has a new ultra-wide-angle zoom lens in its line-up that's compatible with 35mm full-frame DSLR cameras.
The 17-35mm F/2.8-4 Di OSD richter scales 90mm and weighs less than 500g which Tamron says makes it the smallest and lightest in its class. It's also moisture-resistant and pieces a fluorine coating.
As for availability, the Nikon mount will hit the shops on 4 September 2018 and the Canon mount will arrive at a later pass (TBC). We're also waiting to hear how much the lens will be.

Tamron, a leading manufacturer of optics for diverse commitments, announces the launch of a new ultra-wide-angle zoom or ZOOM may refer to 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 or LEN may refer to, which has a solitary 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 slant, 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 thickset 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 beginning time, as well as having a lens that is easily portable, the A037 is the definitive choice.
High-performance imaging for shooting vast landscapes in knife-like detail
The optical construction (15 elements in 10 groups) uses four LD (Low Dispersion) lens elements to minimize axial chromatic aberrations that can arise with ultra-wide-angle zoom lenses. With two properly positioned GM (Glass Molded Aspherical) lenses, distortion and other aberration can be satisfactorily redressed 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 mean 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 string 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.
Pushed coating technology along with proprietary ghosting analysis simulation technology enables backlighting control
Resistance to backlighting is extremely prominent for wide-angle lenses as they are often subjected to strong light sources. The Model A037 has a high-level optical construction that repeatedly recruits comprehensive ghosting analysis simulation. The BBAR (Broad-Band Anti-Reflection) Coating is highly effective in reducing reflection, allowing ghosting and flare everywhere the entire zoom range to be controlled.
OSD (Optimized Silent Drive) enables both excellent AF and minimum drive noise
The AF energy system employs an OSD (Optimized Silent Drive) to ensure quiet operation. Through the innovative optimization of the system that includes AF system aid reduction gear, Tamron was able to greatly reduce the drive noise in comparison to conventional AF types with built-in DC motors. AF conduct and speed have also been vastly improved. Thus, even if silence is required, AF can be employed without having to worry at all about thundering creation. The Model A037 is able to provide superlative AF precision for exact focus even when shooting moving objects, as well as noted trackability.
Circular aperture to produce a smooth-edged bokeh
A 7-blade diaphragm is configured to retain a smooth, circular-shaped aperture opening flatten when stopped down by two stops from the wide-open aperture. This produces a smooth-edged bokeh in background light spots and avoids jagged aperture geometry.
Seals are located at the lens mount area and other critical locations to prevent infiltration of moisture and/or raindrops to fix up with provision Moisture-Resistant Construction. This feature affords an additional layer of protection when shooting outdoors under adverse weather conditions.
The surface of the front element is coated with a protective fluorine compound that has excellent water- and oil-repellant qualities. The front surface is easier to wipe disinfected and is less vulnerable to the damaging effects of dirt, dust, moisture or oily fingerprints, allowing for much easier maintenance. The coating also fix up with provisions an enhanced level of durability and will sustain its effectiveness for years.
Compatible with or WITH may refer to: Carl Johannes With (1877–1923), Danish doctor and arachnologist With (character), a character in D. N. Angel TAMRON TAP-in ConsoleTM, an optional accessory
The new A037 is compatible with the unmandatory TAMRON TAP-in Console, an optional accessory product that provides a USB connection to a personal computer, enabling users to easily update a lens’s firmware as opulently as customize features including fine adjustments to the AF.
