Canon has announced a
damn sexy jaw-dropping EF 11-24mm f/4L USM non-fisheye lens, offering an even crazier field of view than the good old Sigma 12-24mm (about 5% wider).
It makes little doubt that Canon wanted their new UWA lens to be wider than the widest till then, which was the Sigma.
Fancy a little spec & MTF chart comparison?
It’s always interesting to compare two lenses with (almost) identical focal lengths, just to have an idea of the manufacturers’ goals with their respective designs.

The 12-24mm f/4.5-5.6 DG HSM will remain the only affordable-for-mortals full-frame option to go wider than 14mm on a DSLR (barring fisheyes).
Now, a professional-grade ultra-wide lens is needed to compete with Canon’s and Nikon’s optics.
An improved 12-24mm f/4.5-5.6 would be nice, but no matter how good it is, the slow and variable aperture would flag it as a consumer-grade lens.
A very well corrected 14-24mm f/4 would be interesting, even though it would be both slower than the Nikon 14-24mm f/2.8, and less wide than the Canon 11-24mm f/4.
A 12-20mm f/2.8 would be even more attention grabbing, but that looks like an extreme optical challenge.
