With the introduction of the EF 85mm f/1.2L Mark II, Canon has made major improvements in their legendary f/1.2L lens including:
  • 1.8x faster autofocus: Autofocus in the EF 85mm f/1.2L Mark II is now fast enough to use in sports and other fast moving action photography;
  • New lens coatings: Flare is markedly reduced which results in better image contrast in unusual lighting situations;
  • Round aperture diaphragm to f/2.5: Results in smoothed out of focus aperture diaphragm patterns at apertures from f/1.4 to f/2.5
  • Electronics changes to support E-TTL II flash function
