I'm not an expert user of electronic ttl flashes. Today I was trying to familiarize with my new 330FTZ using my Z1-p, but I have some doubts. Mainly, I don't understand the following: Setting Hy-P mode on the camera (ttl mode on the flash) I obtain a couple of value (e.g. 1/60 f/5.6). If now I set the camera on Hy-M mode, setting 1/60 f/5.6, the leds of the camera indicate a big under-exposition. What's the problem?
