The Canon EF-mount SP 150-600mm f/5-6.3 Di VC USD G2 from Tamron is a 4x zoom covering telephoto to super telephoto perspectives. Complementing the long reach is an optimized optical design that features three low dispersion (LD) glass elements to reduce chromatic aberrations and color fringing throughout the zoom range. eBAND and BBAR coatings have also been applied to reduce ghosting and flare when working in strong, backlit lighting conditions. A conventional zoom lock is also featured to prevent barrel extension during transport. Suiting handheld shooting situations, Vibration Compensation (VC) is a 4.5-stop-effective image stabilization mechanism that helps to reduce the appearance of camera shake for sharper results when working with slower shutter speeds. Benefitting its use outdoors, the lens also features a moisture-resistant construction along with a fluorine-coated front element to guard against dirt, dust, moisture, and smudging from affecting image quality. The ergonomic and durable metal construction of the lens also incorporates textured focus and zoom rings, and a removable, rotating tripod collar with an Arca-type compatible foot is supplied to better enable shooting from tripods and monopods. Spanning a versatile, long-reaching range, this tele-to-super-tele zoom is designed for full-frame Canon EF-mount cameras, and can also be used with APS-C models where it will provide a 240-960mm equivalent focal length range.Both eBAND and BBAR coatings have been applied to suppress ghosting and lens flare for improved contrast when working in backlit conditions. 

Three separate VC modes are also available to suit various styles of shooting: Mode 1 is a balanced setting for general use, and promotes both a stabilized viewfinder image and stabilized results; Mode 2 is designed exclusively for panning movements; and Mode 3 is optimized to stabilize only during capture without stabilizing the viewfinder image. A FLEX ZOOM LOCK mechanism enables you to lock the zoom at any position to prevent unwanted zoom extension during use. A conventional zoom lock switch is also featured, which locks the zoom in place at the 150mm position to prevent zoom extension during transportation. The durable metal barrel uses a curved, ergonomic shape for easy handling, and both the zoom and focus rings are textured for improved grip. An electromagnetic diaphragm is used for more precise and consistent exposure control, especially when shooting at high continuous shooting rates.
