The Canon EF 70-300mm f/4-5.6 is a 22 ounces camera lens with 3-stop image stabilizer for minimizing camera shake. The EMD (Electro-magnetic diaphragm) feature allows users to create better background when using larger apertures. The Super Spectra lens helps to suppress ghosting and flare.
Some users may find the lens inappropriate as it extends when zooming and shows noticeably worse picture quality in low-light situations. Nevertheless, its speed is terrific and the optical quality is more than acceptable when ample light is present. The Canon EF 70-300mm f/4-5.6 is a great lens when you are on a budget and want to learn basic parameters, such as ISO settings, white balances, shutter speeds, aperture and others.
