Tamron Announces Development of 17-50mm f/4 Di III VXD Lens
Tamron is expanding their Di III lens lineup with the announcement of a 17-50mm f/4 Di III lens. This focal length for the E-mount is especially desirable for those photographers seeking a highly portable “walkaround” lens for travel and portraiture.
The lens features VXD autofocus for wide and accurate coverage. This technology is similar to the ultrasonic type found in certain mirrorless and DSLR cameras, giving the lens healthy speed and a degree of accuracy that Tamron claims to be “rivaling that of more-expensive single-lens reflex cameras.”
The lens also features eBAND coating to reduce flare and ghosting, allowing maximum clarity and true color representation. Tamron added that this coating makes the lens “sturdy enough to allow reliable performance even in locations in which shooting conditions are severe or challenging.” It also has an aperture diaphragm boasting a curved 7-blade design to ensure attractive bokeh.
Tamron reduced weight and size with a lightweight design which makes the lens take up little space and even more portable. It weighs in at only 12.9 ounces, making it 1.6 ounces lighter than its longer-reaching 24-70mm f/2.8 Di III RXD counterpart.
The lens is expected to ship sometime in May 2020, although the price is yet to be announced. The 17-50mm f/4 Di III VXD lens will be available for Canon, Nikon, and Sony E-mount cameras, with Sony Alpha owners taking advantage of the share the lens’ autofocus actuation, which in this case will be driven by the camera body.
