The power level is relative to what :
a) the 500FTZ's maximum power ? b) the metered reading taken by the camera ?
If using multiple flashes e.g. 2 x AF500FTZs can you set the power level of one flash relative to the other and still maintain TTL operation using the 5p sync cord system. E.g
Use a main light with a fill light at 1 or 2 stops below the main light.
If i did not explain myself clearly pls say say so and i'll rephrase
Tnx
