Comparison of New and Old 16-35mm Against 17-40mm and Primes
Select Wide or Tele from the above menu.
Summary Conclusions
The new 16-35mm has a small improvement in micro contrast within the 15mm image circle radius (APS-C is 13mm) but a substantial improvement for full frame edge and corner over the old lens at the wide angle end.
The centre tele performance of the 17-40mm is still a lot better than the new lens although this is often not reflected in lens tests.
The centre wide performance of the 17-40mm is still a little better than the new lens although the new 16-35mm should give better full frame corner performance beyond 20mm.
In general the improvement within the APS-C region is small enough that lens to lens variations mean that individual lenses of each type may or may not be sharper.
Fine detail rendition is very similar to the old 16-35mm
