Generally speaking, there are a lot of aspects to consider, including the
one above, but this can lead to another endless discussion, with anyone
trying to guessweigh the different problems.
However, the case we are discussing (that 17-40mm Canon lens) looks more
like a lens fault (very good up to a certain field and then sucks all at
once) that a progressive worsening due to a progression in angle of
incidence of the light (occurring for certain, but apparently not being the
main problem in that picture). At least, that's my idea.
...and even if it *isn't* a lens fault (and I do think it is), one can't
presuppose that digital sensors aren't going to improve over the years.
In fact, one would have to be a fool to think they aren't.
Of course, and potentially there might be some technology that would
improve the angle of light problem, like some new way of getting the
microlenses to compensate, or maybe a non-vertical approach to the
photosite electronics as one approaches the edge of the chip. The
quickest way to improve it would be to make the lens opening larger, but
that would obsolete many old lenses which of course is probably not
going to happen.
