(From Tokina lens literature) The AT-X 235 AF PRO is a wide-angle zoom lens that will produce dynamic images, which are sharp from edge to edge. The fast, constant maximum aperture of f/2.8 makes wide-angle photography, like reporting, effortless in difficult lighting situations such as indoors or at dusk.

Two pioneering all-glass aspherical lens elements, one front and rear, (F&R aspherical) are employed to eliminate wide-angle spherical astigmatism and correct edge/marginal light rays for superb image quality. Hoya Corporation, the world's largest optical glass manufacturer, has created a micron-tuned precision molding technique with the accuracy to form aspherical surfaces to the thousandths of a millimeter. These aspherical elements, as well as 11 more of the remaining 13, receive Tokina's unique multi-coatings to further improve optical performance.

Continuing the tradition of AT-X, this AT-X PRO series lens boasts a solid, all metal construction using duraluminum alloy. Tokina's Focus Clutch Mechanism allows maximum AF response and sensitivity while focusing manually.

    Sharpness, contrast, great MF feel, fast aperture
    High, but correctable CA, long minimum focus distance

    Using this lens on my Nikon D700, I find it to be an excellent, if oft overlooked, zoom lens. While the frame is a bit soft at the edges at f/2.8, it sharpens up nicely across the board with stopping down. CA is ever-present across the frame, but easily removed either in-camera or in post.

    The weakest point of this lens has to be the minimum focus distance (MFD), which only allows for about 10:1 reproduction ratio, at best, on the 35mm end. This can be a bit limiting of composition, especially at the 20mm end. So don't buy this lens if you are into wide-angle close-ups.

    One of the best aspects of this lens is the focus clutch. While a touch fiddly to engage (one must first focus to infinity or MFD with AF, then move the ring to the right setting, and pull back), it allows the lens to have a buttery smooth damped feel in MF, yet focus very fast in AF. The MF is so good that I enjoy using it on my FM2. In this regard, it is like two lenses in one.

    The build quality otherwise is very high, with tough-feeling metal all over. The focus and zoom rings have nicely differentiated patterns, and the hood is even lined with felt.

    Overall this is a very good lens for full-frame photography, with much better corner performance than its' fixed 17mm cousin. At the bargain used prices it sells for, it is a real bargain.

    Beautifully built, cheap secondhand, very sharp
    A little heavy

    I have never used a Tokina lens on Digital.

    They do work, very well, despite the lack of Hyper-Nano coatings et-al!

    I did have the 28-70 ATX Pro for film long ago, a truly great lens.

    I am not a great user of mid range focal lengths and there is no way I could justify the expense of something like a 17-40L for my 30D, especially given the amazing price hikes in the UK in these strange times.

    I located a copy of this lens used at my friendly local Camera Store and took a chance.

    It is excellent. Sharp, contrasty and flare is no problem at all. Weak at 2.8 , but no surprise there. From F4 on it is very, very good.

    At one third the current price of a 17-40L I have to say I am delighted. It is up there on the same level in all but focusing speed and close focusing ability.

    For only a little more than the price of an 18-55 kit lens I have a fast well built third party lens that wont disappoint.

    Find a used one and you have a real bargain!
