EF 70-200mm f/2.8L USM
For years, the most popular professional lens in the entire Canon line-up. Superbly sharp and versatile, its constant f/2.8 maximum aperture makes it a favourite of photojournalists and low-light shooters. Four UD-glass elements contribute to its excellent performance. Full compatibility with the EF Extenders 1.4x II and 2x II extends its usefulness, and it’s also compatible with the EF Extension Tubes 12 II and 25 II, and the 77mm Close-up Lens 500D.
