As part of the L series, the Canon EF 70 to 200-millimeter f/2.8L Image Stabilization III UltraSonic Motor Lens is a must have for professional photographers especially. The lens works best outdoors, even in low light conditions, which makes it perfect for low light landscape shots. Indoor lighting, on the other hand, is not ideal for this lens. If you enjoy shooting sporting events or fast-moving objects, be aware that the focal ring of the EF 70 to 200-millimeter L lens has been known to loosen up over time, which will impact the quality of the image along with how quickly the lens can follow your fast-moving subject.

The Canon EF 70 to 200-millimeter f/2.8L Image Stabilization III UltraSonic Motor Lens has excellent image quality overall, and the f/2.8 maximum aperture of the lens allows for fast shutter speeds and a beautiful background blur across its entire zoom range. While the autofocus feature of the lens may not be the quickest of the Canon lenses, it is quiet when it is used for video recordings, so unnecessary background noise from the autofocus feature will not be a concern. Along with having no noise disturbances, the combination of Canon's Air Sphere Coating and an updated Super Spectra Coating have significantly reduced the chances of lens flare and ghosting in images for the Canon EF 70 to 200-millimeter f/2.8L Image Stabilization III UltraSonic Motor Lens. Any professional who wishes to add another L lens to their collection should purchase the EF 70 to 200-millimeter f/2.8L Image Stabilization III UltraSonic Motor Lens.
