At the CP+ trade show, Kenko Tokina will be showing a mock-up of its newest full-frame lens, the Tokina SD 70-200mm f/4 (IF) FX. This constant-aperture telephoto zoom features a ring-type ultrasonic focus motor and optical image stabilisation. Measuring 168x80mm (length x maximum diameter), the Tokina AT-X Pro SD 70-200mm f/4 (IF) FX lens is a bit thicker but nearly 5mm shorter than Canon’s popular EF 70-200mm f/4L IS USM. Additionally, the Tokina lens can focus somewhat closer (its close-focus point is at a distance of 1m from the sensor plane), although its maximum magnification is unknown at the time being. The release date and MSRP have not yet been revealed either.
