I wonder how Canon will slot in a 14mm prime. I hope Canon goes like sigma with a 14mm f/1.8
I believe Canon has three options:
1. go wider just like with the UWA zooms. I imagine an RF 12mm
2. keep 14mm, but give it more light like F2 at least
3. Design a completely new and super light 14mm F2.8.
With the zooms getting wider and the RF 16mm F2.8. about to come, I think option No 1 makes a lot of sense. Give it F2 and it would be a killer astro lense
