Alex I own the 17-35 and I had before the 20-35. The former has slightly better corrected distortion at 17 and 20mm but less sharpness. Of course, obviuosly, has a wider range and USM as the later cannot be MF focused when AF is engaged. I think the 16-35 has recovered the lost sharpness but I do not foresee buying it. If one consider best sharpness and distortion as a true priority over convenience then the way is to buy 14,20,24,28 and 35 primes.
