Canon EF 16-35mm F2.8L III USM:
Looking to take things up a notch, Canon's EF 16-35mm f/2.8L III USM Lens embraces a revamped optical design with modern coating technologies that promise improved outer and corner sharpness along with minimal distortion and enhanced peripheral illumination. A member of Canon's legendary L series, this full-frame 16-35mm delivers outstanding image quality and a professional-grade durability. It also offers a fast and constant f/2.8 maximum aperture for consistent performance and light transmission throughout the zoom range.

With the incorporation of two large diameter GMO dual surface aspherical elements and one ground aspherical element, the lens will minimize distortions throughout the zoom range as well as maintain edge-to-edge sharpness and illumination. Along with those elements, the lens utilizes two Ultra-low Dispersion glass elements which minimize chromatic aberrations. Also, it uses both a Subwavelength Coating and an Air Sphere Coating to minimize flare and ghosting.

Canon EF 24-70mm F2.8L II USM:
This redesigned EF 24-70mm f/2.8L II USM Zoom Lens from Canon ups the ante for optical performance for a professional standard zoom lens. It has one Super UD lens element and two UD lens elements that minimize chromatic aberration in the periphery at wide-angle, as well as reducing color blurring around the edges of the subject. In addition, two types of aspherical lenses are combined to help reduce spherical aberration over the entire image area, as well as through the full zoom range. Optimized lens coatings help ensure exceptional color balance while minimizing ghosting.

A ring-type USM and high-speed CPU with optimized AF algorithms ensure silent, fast autofocusing. The lens is constructed with improved dust sealing and water resistance, while fluorine coatings on the front and rear lens reduce fingerprints and smearing. A circular 9-blade diaphragm gives beautiful, soft backgrounds. A zoom lock lever locks the zoom position at the wide end for safe transporting while attached to an EOS DSLR camera over the shoulder.

Canon EF 70-200mm F2.8L IS III USM:
One of the most versatile lenses available, the EF 70-200mm f/2.8L IS III USM from Canon is an L-series telephoto zoom distinguished by its bright design and advanced optics. Ideal for a variety of subjects ranging from portraiture to sports, the fast constant f/2.8 maximum aperture excels in difficult lighting conditions and also offers increased control over depth of field for isolating subjects. The optical layout makes use of one fluorite element and five UD elements to suppress chromatic aberrations and color fringing in order to realize a high degree of clarity throughout the zoom range. An Air Sphere Coating is also featured, and works to reduce flare and ghosting for greater color fidelity and contrast in all conditions.

Complementing the speed and optics is an Optical Image Stabilizer, which compensates for 3.5 stops of camera shake to better enable working handheld and in low-light situations. A ring-type USM and internal focusing mechanism also afford quick, quiet, and accurate autofocus performance, as well as full-time manual focus override. Additionally, this lens is weather-sealed for use in trying environmental conditions.
