Newly merged Kenko-Tokina has revealed the Tokina SD 17-35mm F4 AT-X PRO FX, a semi-fast wideangle zoom for full frame cameras.
The f4 maximum aperture makes it easier to produce a smaller lens with fewer aberrations, to sit alongside its 16-28mm F2.8 PRO. The lens features SD glass, which according to the company, offers similar properties to fluorite elements, as well as its ‘silent drive module’ AF motor and high-precision AF position sensor for fast, accurate focusing. Details of pricing or availability are yet to be released.
