1) Light falloff (vignetting) is a HUGE problem, not just in the
corners but even along the edges. It's definitely very noticeable
in the images, especially those with a bright blue sky. Honestly,
this is the worst I've ever seen of all of the lenses I've ever
used.

I guess you mean at f2.8? This is normal for any fast lens and is
no where near as bad as a fast lens on a full frame camera. On full
frame cameras you get black corners from a lot of lenses, not just
fall off.

A sigma 30mm looks worse, more than a stop fall off, than the 17-55
and the 60mm macro at f2.8 has some fall off.

I guess your advice might be not to shoot landscapes at f2.8 and
then it wont be noticable.

That's good advice in general, falloff or not.

However, one can imagine shooting large interesting foreground objects (e.g., statues) w/ shallow DOF on a bright day w/ lots of sky showing. That's actually not a rare photo situation when traveling.

That said, now that you mention it, I guess I've never shot a fast wide lens on FF before. When I shot film, I was more into telephoto stuff. So all fast wide lenses have this "problem"? That's interesting. There's no lens that can shoot
