Sigma AF 17-50mm f2.8 EX DC OS HSM (Canon)

The EF 300mm f/2.8L IS II USM Lens from Canon is the perfect choice for nature, wildlife, and sports photographers. Using the three mode Optical Image Stabilization allows you to shoot at shutter speeds 4 stops slower, and the advanced third IS mode activates only when the shutter button is fully pressed, so you can pan with fast-moving subjects without the IS function interfering with composition and framing.

The Canon EF 24mm f/2.8 IS USM is a versatile wide-angle prime characterized by its fast performance and image-stabilized design. Also, a ring-type USM realizes quick, quiet, and smooth autofocus performance along with full-time manual focus override. Wide-angle 24mm f/2.8 lens is designed for full-frame Canon EF-mount DSLRs, however, it can also be used with APS-C models where it provides a 38.4mm equivalent focal length. One aspherical element helps to suppress spherical aberrations and distortion for a high degree of sharpness and accurate rendering. An Optical Image Stabilizer helps to minimize the appearance of camera shake by up to four shutter speed stops to better enable working in low-light conditions and with slower shutter speeds. A ring-type Ultrasonic Motor (USM), along with a rear focusing system, is employed to deliver fast and precise autofocus performance as well as full-time manual focus override.

Canon EF 100-400mm f/4.5-5.6L IS II USM Lens is part of the esteemed L-series developed for full-frame EOS DSLRs. One fluorite element and one Super UD element have been incorporated into the lens' construction, and both help to reduce aberrations and distortions throughout the zoom range in order to deliver notable clarity, image sharpness, and faithful color reproduction. An Air Sphere Coating has also been applied to lens elements in order to reduce lens flare and ghosting for more contrast-rich imagery. Benefitting the optical components of the lens, a four-stop effective Image Stabilizer helps to minimize the appearance of camera shake and can be dedicated to different styles of shooting. Furthermore, a redeveloped rotation-type zoom ring pairs with an internal focusing mechanism, and an Ultrasonic Motor, to deliver quick and intuitive handling to benefit handheld shooting. Positioned as a versatile option for sports and wildlife photographers, this lens' list of attributes make it a viable telephoto zoom for a variety of shooting applications. Housed within a weather-resistant barrel, this lens also features fluorine coatings on the front and rear elements for protection against fingerprints and smudges from affecting image quality. Zoom control is complemented by a dedicated tension ring for adjusting zoom torque. Additionally, other refined design elements include a tripod collar that can be attached or detached with the lens mounted to the camera and an included lens hood that permits easy control over specialty filters with the hood in place.

The EF 24-105mm f/4L IS II USM is a Canon L-series zoom covering wide-angle to short-telephoto focal lengths and featuring a constant f/4 maximum aperture. Individual elements feature an Air Sphere Coating, too, to suppress flare and ghosting for greater contrast and color accuracy in harsh lighting conditions. Additionally, this lens is weather-sealed and has a protective fluorine coating on the exposed elements for use in trying environmental conditions. Standard wide-angle to a telephoto zoom lens is designed for use with full-frame Canon EF-mount DSLRs, however, it can also be used with APS-C models where it will provide a 38.4-168mm equivalent focal length range. An Air Sphere Coating has been applied to individual elements to reduce backlit flaring and ghosting for greater contrast and color fidelity in strong lighting conditions. Rounded ten-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.
