Sunpak states that their PZ40X II provides i-TTL capability but also states that none of their flashes are compatible with Nikon CookPix cameras. The Coolpix 8800 is the only one of the Coolpix series that has i-TTl but I cannot get confirmation, that the combination will work fully. Does anyone have experience or knowledge with this Sunpak flash. Does it provide full i-TTL functioning? I just can't afford the Nikon SB600 or 800.
