• Canon EF 16-35mm f/2.8L II USM:
  • 82mm filter allows polarisers without vignetting; weatherproofed; ($A2095 online)
  • corners almost as sharp as centre at f/4 on full frame but still soft wide open.
  • best resolution at 24mm but CA can be a problem
  • barrel distortion at 16mm
  • better image quality than the EF 17-40mm f/4L, but at 24-35mm, neither of these comes close to a EF 24-70mm f/2.8L
  • at last Canon has a lens that beats the Olympus OM 18mm but it still has problems in the corners on a full frame sensor.
