Canon’s EF 100-400mm f/4.5-5.6L IS USM debuted in 1998, and over a decade and a half later we’re still waiting for a replacement. But we might not be waiting very much longer at all. In fact, recent rumors now backed up by the first leaked image indicate that this lens will arrive this month.
In addition to the leaked image, which comes from the notoriously reliable Digicame-info, the folks at Canon Rumors have been compiling specs and information on the new lens over the past couple of weeks as well.
According to CR, the new 100-400mm is being tested in the wild as we write this, and comes with several improvements over the previous iteration, pictured below.
It’s supposedly smaller than the current 100-400, will feature a zoom ring design instead of push/pull, touts significant improvements to AF and IS, and is similar in design to the EF 70-300mm f/4-5.6L IS (confirmed by the image above).
It’s getting to the point with these rumors — which we’ve held off sharing over the last few weeks for lack of info — where a grain of salt is more of a formality than a necessity. Don’t take all this info as gospel by any means, but if you’ve been thinking of picking up the much-loved older 100-400mm, we’d wait if we were you.
