Wide Zoom Range
The new Tokina AT-X 12-28mm F4 lens has a super-wide to standard zoom range while maintaining a constant fast f/4.0 aperture. This makes ita very versatile lens for different photo applications such as scenery, street scenes photography and event coverage. The lens is designed for DSLR cameras with APS-C (DX) sized sensors.
New Optical Design
A new optical design using aspherical elements and super-low dispersion glass matches even the highest mega-pixel DX sensors cameras available today.
One asphericallenselement is positioned in the front group. This together with another precision molded glass aspherical lens element placed in the rear group ideally focuses marginal light rays andmaintains sharpness at the edgeswhile also correcting distortion. The use of two different SD(Super-low Dispersion)glass elements,typeFK01 and FK03,correctschromatic aberration. The combination of all these specialized elements in the optical design yield excellent sharpness and color.
New auto focus mechanism
The new AF “GMR magnetic precision” control sensor is capable offastauto-focus. Tokina placed the new sensor closerto the drive unit in the lens for faster communicationbetween the controller and AF motor. This combined with the motor's high-precision focus control yields faster, more accurate auto-focus.
Additionally, a brand new “SD-M” (Silent Drive-Module) has greatly lowered the sounds emitted by the auto focusdrive system allowing for much quieter AF. Both Canon and Nikon mounts have a built-in AF motor to make them auto-focus compatible with all current camera bodies.
Compact body design
The Tokin AT-X 12-28mm F4 compact designmakes the lens easy to carry and handle. Manual focus is achieved through Tokina's one-touch focus clutch AF/MF mechanism. Simply slide the manual focus ring forward for auto-focus or back for manual focus operation. The lens focus ringis damped in the manual mode for smooth and precise focusing.
In addition thelens has a 77mm filter size allowing filters such as the Hoya HD low-profilecircular polarizer or UV to be used.

Canon EF 100-400mm f/4.5-5.6L IS II USM
The EF 100-400mm f/4.5-5.6L IS II USM lens delivers a superb combination of cutting-edge performance, compact construction and brilliant resolving power that’s great for sports and wildlife photography. The lens features one fluorite and one super UD element to help provide impressive contrast and resolution with reduced chromatic aberration across the entire zoom range. Canon’s new Air Sphere Coating (ASC) helps significantly reduce backlit flaring and ghosting, while fluorine coatings on the front and rear lens surfaces help lessen smears and fingerprints. A 9-blade circular aperture renders beautiful, soft backgrounds, and a 3 mode (standard, panning and exposure only) Optical Image Stabilizer provides up to 4 steps* of image correction. The new inner focusing AF system helps ensure fast and accurate focus down to 3.2 ft. with a .31x maximum magnification. Usability enhancements include a rotation-type zoom ring with adjustable zoom torque for more precise, customizable zoom performance, a redesigned tripod mount that can be attached and detached without removing the lens from the camera, and an all-new lens hood with a side window that makes it simple to adjust specialty filters-like polarizers-without the need to remove the hood. Ruggedly constructed with advanced dust and water sealing for durability in a range of environments, the EF 100-400mm f/4.5-5.6L IS II USM lens is a stellar performer with refined controls for a wide variety of situations.

Canon EF 100-400mm f/4.5-5.6L IS USM
L-series super telephoto zoom lens equipped with an Image Stabilizer. The fluorite and Super UD-glass elements largely eliminate secondary spectrum. The floating system also ensures high picture quality at all focal lengths. The Image Stabilizer has two modes and it is compatible with Extenders 1.4x II and 2x II.
Despite the large maximum aperture, the lens remains compact. Lens group 5 moves for rear focusing, and sharp, crisp pictures are obtained at all apertures. The background blur is ideal for portraits. The USM auto focuses the lens quickly and quietly.
