Canon EF 400mm f/2.8L IS III USM Lens to be Announced ahead of Photokina 2018
Canon is planning to announce at least two new “big white” super telephoto prime lenses ahead of Photokina 2018. One of the big white lenses is now confirmed: it is the Canon EF 400mm f/2.8L IS III USM lens.
The second one from Canon is still unknown at the time of writing, but it will be a version III lens, probably EF 300mm f/2.8L IS III USM lens, EF 500mm f/4L IS III USM lens or EF 600mm f/4L IS III USM lens.
The main upgrades for these lenses will likely focus on weight reduction and updated coatings. And the optical formulas is expected to remain about the same.
Reminder: In June 2018 Canon officially announced the new EF 70-200mm f/2.8L IS III USM and EF 70-200mm f/4L IS II USM lenses.
