I used the F280 in Brazil some months ago. I wanted to use fill-in flash,
so I brought that one instead of the good ol' T32. I found the OM 4 Ti
often saying "underexposed" when I think the F280 should have enough power
to give a good exposure. In my opinion, the F280 does not have the listed
guide # of 28 (meters, 100 ISO). (I am talking about normal TTL flash
here.)
Alas, nobody makes a better FP flash for Olympus. :-(
