Originally posted by imtheguy I just checked B&H out of curiosity and the prices are very reasonable currently (IMHO) at $199 and $389 for the non-sealed units. That would be my choice if I was buying.
If it was just weather sealing then I would be happy with the old flash units, but the new "II" versions also have improved PTTL firmware for better flash exposure consistency. Many of us have run into flash exposure issues with the original 360 and 540 flashes (and let's not forget the plastic foot). I sold my original 360 flash and ended up buying two Metz 52 AF-1 units.
The Metz is more consistent, but it's still not perfect 100 percent of the time (less so with HSS). I don't know if the AF-360FGZ II and 540 II are any more consistent than the Metz, but they are supposed to be more consistent than the original 360 and 540.
