Unveiled: Two New Canon Wide-Angle Zoom Lenses
Canon has announced two impressive new wide-angle zoom lenses: an EF-S mount lens to satisfy APS-C camera users and a full-frame EF mount L-series lens.
The EF 16-35mm f/4L IS USM Lens has been introduced as an alternative to the current 16-35mm f/2.8L II USM lens and incorporates an Optical Image Stabilizer. While the f/2.8 lens offers a faster maximum aperture, the stabilization system in the new lens compensates up to 4 stops to reduce blur when shooting with slower shutter speeds. And as an L-series lens, it provides the best Canon has to offer in terms of dust and water resistance, as well as overall durability.
Optically, its combination of three aspherical and two UD lens elements minimizes aberrations throughout the zoom range and contributes to the creation of beautiful high-contrast images. A flourine lens coating reduces ghosting and flares and its circular 9-blade aperture enables pleasing background blur. The EW-82 Lens Hood is included with the lens to block stray light from entering the lens.
An inner focusing system, combined with ultrasonic autofocus motor (USM), realizes fast, quiet, and accurate autofocus and, when necessary, full-time manual focus is available. The minimum focus distance throughout the zoom range is 11" and its filter thread diameter is 77mm. L-series lenses are designed to meet the utmost in physical and optical standards and are regarded as a high point in the Canon DSLR lens line. The EF mount of this 16-35mm f/4L is designed for full-frame cameras, such as the current Canon 1Ds and 6D cameras and those of the 5D series.

Switching over to the APS-C side of the fence, Canon has brought forth the EF-S 10-18mm f/4.5-5.6 IS STM lens to shoot with current crop-sensor DSLRs, such as the 7D, 60D, 70D cameras, and those in the Rebel line. The 10-18mm offers advantages over the current EF-S 10-22mm lens in that it is significantly more compact and lightweight and it provides image stabilization.
Like the above 16-35mm lens, the EF-S 10-18mm is considered an ultra-wide-angle zoom lens and its 35mm focal length equivalence is 16-28.8mm. It optimizes its 4-group optical design to maintain a compact form factor that sits well on the generally more compact APS-C camera bodies. The optical system comprises a “large-diameter” lens element, as well as one aspherical and one UD element to control aberrations and create high-resolution, high-contrast images. Enhanced lens coatings also improve color balance while minimizing ghosting and flare.
As mentioned, the 10-18mm lens features Optical Image Stabilization for up to four stops of compensation against the blur from camera shake and its rear focusing system with stepping motor (STM) and improved autofocus algorithm provide fast AF and support the Canon EOS Movie Servo AF function for smooth and quiet continuous AF when shooting video. Full time manual focus is always available, even when in AF mode, and its minimum focus distance is 8.6". An optional dedicated lens hood, the EW-73C Lens Hood, will help to deflect unwanted light, reducing flares as well as protecting the lens from damage due to accidental impact.
