The Canon EF 70-200mm f/2.8L USM is not a new lens, but still offers very good performance on both full-frame and APS-C DSLRs. Optical construction includes four UD (ultra low-dispersion) elements to correct chromatic aberrations, and it is compatible with Canon's Extender EF 1.4x II and 2x II teleconverters. Canon did a nice job of integrating the setup and it will replace the 400 f2.8 on my second body for daytime sports and well illuminated night sports; having a 200-400 native range with 280-560 f5.6 extender range makes it perfect for covering action over most of a soccer pitch.
