Fractional and Watt Second Equivalents for Power levels 1-9Updated 2 days ago
Each power level designates 1 stop or 1/2 the output of the level just above it.
Power level 9 is 1/1, 8 is 1/2, 7 is 1/4, and so forth down to level 1, which is 1/256 of the full output. Another example to help illustrate this is a situation in which moving from power level 9 to 8 is a one-stop light change. If your camera were at f/5.6 at level 9, an equivalent exposure would be f4 at level 8.
Power Levels- FJ systems employ levels 1 through 9, with 9 being the highest. Each number represents 1 stop (½ or twice the previous numbered output).
