We're told at least two new “big white lenses” are coming ahead of Photokina 2018. We're not sure at the time of writing this what the new lenses will be.
Will we finally see the EF 600mm f/4 DO IS?
We weren't expecting new big white lenses until 2019, but we may be getting a year long rollout of updated supertelephoto lenses. Optically, I'm not sure how these lenses can get much better, but they could certainly use some weight reduction in light of Nikon and Sony's lighter offerings with certain supertelephoto lenses.
More to come…
