Canon 70200f4 Generation Time to Market

August 24, 2006. Canon, in conjunction with the latest entry-level digital SLR 400D, released an EF lens "EF70-200mmF4LISUSM", which went on sale in mid-June 2006, 165438+, and went on sale in China in 2007. In addition, Canon 70-200mmf/4 is a telephoto zoom lens with a long focal length range, which is suitable for shooting distant scenery, animals and sports. The aperture of the lens is constant f/4, which can keep the same amount of light in different focal lengths, allowing photographers to shoot at a faster shutter speed in dark scenes. Moreover, the lens also has a certain anti-shake function, which can effectively suppress the jitter caused by hand-held shooting and improve the shooting clarity.
