We're told that the Canon EF 35mm f/1.4L II is “done” and ready for production. An announcement date is unknown as Canon is still playing catch-up on some other in demand lenses such as the EF 100-400mm f/4.5-5.6L IS II.
- Dust & Weather Sealing
- All the latest coatings
- Longer than the current version
- Smaller diameter than the current version
- Smaller filter thread
- New hood design
- Unknown weight
I think a fall announcement is likely, and I don't expect such a lens to be announced alongside a camera body.
On a side note. I'm heading to Chicago this weekend and will be using the current EF 35mm f/1.4L exclusively on the EOS 5DS.
