Tamron is releasing a new lens, Tamron 17-35mm F/2.8-4 DI OSD on September 5th, 2018 according to B&H Photo Video. This lens is really hitting the sweet spot by the sounds of it, and will definitely be heavily reviewed by the photographer’s community. Since I used to shoot with Canon, I used the Canon 17-40mm F/4 lens as my primary walk-around. I also used it heavily for astrophotography, even though it’s f/4 aperture is not ideal for that scenario. But now, with this new lens from Tamron, I believe it’ll be the best replacement for my Canon 17-40mm. Based on specs alone, stated below, this lens could really become the powerhouse for many photographers. I have used a Tamron lens in the past, the 17-50mm, and it was an absolutely beautiful lens. The only reason I sold that lens, was because I switched to a full frame body. This new lens from Tamron will be available for Canon and Nikon Full Frame camera’s. There is also rumor that a Sony E-Mount version will be available in the near future.
Tamron’s technical description of the lens:
The 17-35mm F/2.8-4 Di OSD (Model A037) is an ultra-wide-angle zoom lens that combines superb image quality with outstanding portability as the lightest and smallest size in its class.* It uses four LD (Low Dispersion) lens elements to minimize axial chromatic aberrations. And with two GM (Glass Molded Aspherical) lenses it can not only provide the sharpness and contrast demanded by high-end lenses, it can also handle peripheral point image reproducibility. Furthermore, it has repeatedly gone through our proprietary ghosting analysis simulation employed to resist backlighting problems from strong light sources to which wide-angle lenses are often subjected. Along with an enhanced high level optical construction, the lens has BBAR (Broad-Band Anti-Reflection) Coating highly effective in reducing reflection and controlling ghosting and flare. The Minimum Object Distance (MOD) for the entire zoom range is a short 0.28m (11 in), so you can still enjoy the background blurring effect when shooting full open aperture and close-up with this ultra-wide-angle zoom. The Model A037 also has a circular aperture that gives you beautiful circular bokeh.
The lens is expected to be released on September 5th, 2018 at the pricepoint for $599. Are you considering to buy this lens?
