The technical Details Behind This Lens
Distinguished by its bright design and advanced optics, this lens is certainly one of the most versatile lenses from Canon. It is an L-series telephoto zoom lens, making it ideal for different photography applications. The fast maximum aperture of f/2.8 performs superbly in difficult lighting conditions, offering increased control over depth of field, for working with selective focus techniques.
Designed for full-frame Canon EF-mount DSLRs, the lens is also compatible with APS-C models. With the latter, the lens provides a 112-320mm equivalent focal length range. The lens construction is impressive, with the presence of one fluorite and five ultra-low dispersion elements. These work together to reduce colour fringing and chromatic aberrations, delivering high-quality imagery.
The lens has a weather-resistant structure, protecting it from dust and moisture. This allows worry-free usage of the lens in tough shooting conditions. The front and rear elements of the lens are further secured with a fluorine coating, protecting it from fingerprints and smudging.
Top Three Reasons We Think You Will Love The Lens
- The elements of the lens are coated with Air Sphere Coating (ASC). This reduces the effect of backlit flaring and ghosting. It also maintains light transmission and high contrast in strong lighting conditions.
- The lens features an in-built optical image stabiliser, which cuts down the appearance of camera shake by up to 3.5 shutter speed stops. This not only helps you work better in low lighting conditions but also with slower shutter speeds.
- The lens flaunts a rounded diaphragm with eight blades, which gives out a subtle impressive bokeh, thus enhancing the quality of your images .
