Looking for a Flash for my Fuji S1 Pro camera
I think you'll struggle to find any flashgun that operates well on TTL on the S1. I still use the S1 professionally - am waiting for better details on the S3 - and when my Metz finally gave up, I bought the Nikon SB80DX, which works brilliantly in A mode, but forget TTL!
I guess the 800 has now superceded the 80 and a good flashgun will cost more than your S1 is worth, but it hasn't turned into a bad camera just because there are newer tech models on the market . . .
