The Canon 70-200mm series consists of 4 lenses, but in this article I will focus only on the most popular of these lenses, the 70-200mm f/2.8L IS II telephoto zoom lens. The 70-200mm f/2.8L IS II is arguably the most popular lens in the L-series lineup and once you start shooting with it, it’s not difficult to see why.
The sharpness of this lens is, for a lack of a more technical term, fantastic. It is sharp from center to edge, from maximum to minimum aperture, and from 70-200mm. When shooting with it, I never think “I should stop down a little because I want it to be super sharp.” Images at its maximum aperture of 2.8 are plenty sharp.
