Question: canon 100-400 is ii review?
Answer: If you shoot with a Canon camera and want a telezoom, the Canon EF 100-400mm f/4.5-5.6L IS II USM is an excellent, albeit pricey, option. It's fairly compact and light when you consider its reach, doubles as a decent macro lens, and is very quick to adjust focus, especially if you utilize its focus limiter function.
