New reports suggest the replacement for the highly regarded EF 16-35mm f/2.8L II USM lens may be announced in June 2016.
The upcoming Canon EF 16-35mm f/2.8L III will for sure top the lens it replaces. Quoting the source of the rumor:
A person who has used the EF 16-35mm f/2.8L III says it’s every bit as good as the recent L offerings from Canon and “solves the most glaring weaknesses of the current version.”
I think this rumor has a high probability to be reliable. Stay tuned…[via Canon Rumors]
