The long awaited replacement….
We’re told production for the EF 100-400 f/4.5-5.6L IS will be “coming to an end soon”. Production for the replacement will begin sometime in late 2013 or early 2014.
Canon’s lens production has had its share of issues in the last few years with the new super-telephotos and to some extent the EF 24-70 f/2.8L II. We’re told until the EF 200-400 f/4L IS 1.4x production reaches demand, Canon will not be producing the replacement to the long-in-the-tooth EF 100-400. All issues are apparently going to be resolved sometime this fall.
An announcement and release may depend on how fast Canon can sell off existing stock of the 100-400.
