This is the 20-35 constant aperture f:2.8 pro grade zoom. The AT-X 235AF PRO lens uses the latest in lens development technology, using 2 (the front and rear) molded, multicoated aspherical elements which are created through a collaboration with Hoya Corporation, the world largest manufacturer of optical glass. This lens also features the exclusive "Focus Clutch Mechanism". As with all the lenses in Tokina AT-X AF series, the AT-X 235 AF PRO is constructed using all aluminum lens barrels and a chrome plated brass mount plate. The lens elements are made of higher quality HLD (high refraction, low dispersion) glass for higher resolution and contrast.
The lens is quite new, shows no signs of use other than mounting on the camera. It is the latest version Tokina ATX Pro AF lens and comes with both caps, hood and soft padded zippered case. The new price from B&H is US $600. I have lowered the asking price to US $400. I am working on building up my 67 lenses and am starting to sell off items that I don't use so much. I find that I mostly use primes and just don't put much use on the zooms. Bruce Dayton - This message is from the Pentax-Discuss Mail List.
