I actually own the 16-35 and 17-40 and I have had the 20-35 f2.8 and the
17-35 f2.8. Overall the best is the 17-40. None of them, however, is an
outstanding lens but the 17-40 is almost acceptable. With full frame EOS
others -16-35, 17-35 and 20-35- have very soft corners and borders at
2.8 and even the Canon 14mm at f2.8 is soft. Nowadays the only wide zoom
I'm regularly using is the 17-40 but I hope Canon had offered a better
lens in the line of Carl Zeiss 17-35mm f2.8 for Contax N. I think that
there exist enough demand for that even at very high cost. I believe the
best extreme wide images from Canon DSLR are those of EOS30D and 10-22
Canon EFS zoom..
Felix.
