I came across the Effective Flash Range chart on page 90 of the manual.
Is the first number range the aperture, and is the second number after the slash the distance?
ISO Speed............EF-S18-55mg f/3.5-5.6 IS II
..........................EF-S18-135mm f/3.5-5.6 IS
.....................Wide Angle...............................Telephoto
100..................1 - 3.7 / 3.3 - 12.1..............1 - 2.3 / 3.3 - 7.5
200..................1 - 5.3 / 3.3 - 17.4..............1 - 3.3 / 3.3 - 10.8
400/AUTO.........1 - 7.4 / 3.3 - 24.3..............1 - 4.6 / 3.3 - 15.1
