I've seen people touting the F280 full sync flash around on the forum as the be all and end all to automatic flash. I wanted to get an idea of how good it is and how often people use it where a normal TTL flash wouldn't have done the job. I agree that it is a somewhat revolutionary flash, but I'm trying to get an objective view of is it worth the expense of the Om-4ti + the flash? I've used medium format cameras for a while with leaf shutters, so the ability to sync at any speed is not new to me. so, I'd like to know from people who have the flash, what situations you use it for? how you use it (ie. do you use it as a flash or do you try to balance ambient/flash light; how do you know how much of each you'll get). And how often do you use it where a t32 or other flash wouldn't have also done the job. Do you find that you take shots that you wouldn't have otherwise been able to take?
