The first will be an EF-S 10-18 f/4.5-5.6 IS STM. The EF-S 10-22 f/3.5-4.5 would probably stay current even after the new EF-S 10-18 f/4.5-5.6 IS STM is announced. I imagine the new EF-S lens is smaller, lighter and cheaper. The rumor from yesterday seems to have missed the mark on this lens being a constant aperture of f/4. Though more clarification may be forthcoming.
The second will be an EF 16-35 f/4L IS, which will be the exciting one for a lot of people. For the record, a patent for the EF 16-35 f/4L IS appeared in March of this year.
There has been no more information on a new EF 100-400.
More to come….
