a fraction over half stop slower than 70-200mm f4. half stop increments = f4 - f4.8 - f5.6

63/64ths is a fraction.  Why on earth anyone would limit themselves to 1/2 stops with an EOS camera is beyond me when 1/3rd stops are not only available they are what every EOS lens is based on.  Call it what it is.  Its 2/3rds of a stop.
