I'm in the market for a replacement wide angle landscape lens for the 16-35mm f/2.8 L II I currently have. I generally like the focal range, although I don't terribly often seem to use beyond 24mm. The Mark II version of this lens has pretty poor corner performance, and doesn't even really have the best center performance either (which always bugged me, being an L series lens.)
Anyway, the primary use case would be landscapes, however there may also be perspective-oriented stuff as well, utilizing the ultra wide angles to get interesting shots of objects (I like photographing very old rusty farm equipment that is often on display around rural America). This will mostly be used on full frame cameras, and not necessarily just Canon bodies. There may be some astrophotography, however I also have Samyang/Rokinon manual lenses that also fill that role (and to date, I've never seen any other brand that delivers the same kind of corner performance as a Samyang lens...mind blowingly good, small, round, coma-free corner stars with those lenses.) Getting into blue hour photography is also something on my list, which is one of the reasons the f/2.8 lens is on the list.
I am curious to know what other people think about these three lenses. How is the corner performance in particular? Does anyone think 11mm is necessary for wide angle landscapes on FF cameras? One thing in particular is whether any kind of polarization filter use is possible with the 11-24mm. I think it's biggest drawback may be that front element... I had been considering one of the very wide Sigma lenses, however it seems their 12-24mm also has a bulbous front element, and I am not sure there is enough of an IQ improvement over Canon L to justify a different brand.
