Tamron has announced that it is developing a 17-50mm f/4 lens for Sony full-frame mirrorless cameras. The 17-50mm F/4 Di III VXD will be the 16th lens in Tamron's impressive range of options for the Sony E-mount.
With a constant f/4 maximum aperture, the wide-angle zoom will be a great option for travel and for everyday shooting - offering a useful alternative to a kit lens.
