Tokina Japan has added a 'compact' AT-X 17-35mm f/4 Pro FX model to its line up. It's the second AT-X Pro FX (full-frame) lens in its range after the press-orientated 16-28mm f/2.8 released earlier in the year. It will be available in Canon mount first, with Nikon (unusually) to follow later this month. Although it's said to be compact, the lens takes unusually large (82mm diameter) filters to prevent vignetting presumably, but it still weighs 600g and measures 94.5x89mm. There's no word on price or availability from European or American distributors at the time of posting.

The second and tenth elements are aspherical (precision moulded), while the eighth and eleventh are SD (low-dispersion). The rear-most also appears to be aspherical.

These MTF charts show the 17-35mm to be a good performer., especially centrally at 17mm, though the edges drop dramatically. Better overall (average) performance can be achieved at 35mm.
