We've been trying to get more information on lenses coming in 2016 and things are been relatively hard to come by. We're now being told that the non-L 200-600 super zoom we've been talking about is likely an early 2017 lens and will not be announced for Photokina in September as originally planned.
The only new L lens that we can confirm is coming is a replacement to the EF 16-35mm f/2.8L II, which is a lens we've been told is “done” and will be announced some time this year. We were also told that the EF-S lineup would get some attention this year, and that the 10-22 f/3.5-4.5 and 17-55 f/2.8 will see updates and a lower price tag, though we can't confirm this from good sources.
We're also told there are multiple Canon lenses that will get “direct replacements”, and a few would “surprise you”. Though we haven't been able to publish what those lenses would be.
More to come…
