The new EF 100-400 f4.5 – 5.6L IS II USM lens is now available for pre-order. It appears to be a nice upgrade to the present 100-400. It will be interesting to see the tests comparing it (at 400mm) to the EF 400mm f5.6L prime for image clarity. If it performs well, this could be a great lens for the serious amateur wildlife photographer at $2200. I am also interested to know if and how it will work with the Canon 1.4x III extender. Anyway, keep this one in mind if you shoot Canon and are in the market for a nice bird lens!
