That would then suggest a f/2.8 lens (or slightly slower). That would also be consistent with the Canon f/2.8 reviews for example where the chart goes to f/11 on the right, up a stop each set left. So, what f/2.8 prime lenses haven't been published yet? Guess the lens ... - Kodachrome 25 - 11-01-2013 12-40/2.8?
