Hi there, I am currently looking at purchasing a flash speedlight for my Nikon D80 after going years without venturing near flash photography. The only issue is that I am also an analogue lover and would ideally like my purchase to work well with both my D80 and my FM2. After doing some research, this article states that the SB-900 (the unit I was in particular considering) does not feature TTL for film. http://www.photo.net/equipment/nikon/guide-to-ttl-flashes/?p=3 Is that is to say it is totally incompatible with working with a film SLR? The same article leads me to believe that at least some of these units would work with the Nikon F6, a camera I intend to eventually own. For those who own current Nikon DSLRs (as well as the F6 film SLR), i-TTL and CLS is simply a wonderful flash system that can be as simple as just the built-in pop-up flash, one external flash, or it could be a complex, multi-flash system that works in a coordinated manner. If someone could clarify the above quote that would be great. In summary here are my main points/questions when considering which unit I want to buy... - The unit would most likely see more use with a digital camera in live event scenarios etc... - Would rather purchase the SB-900 if it offered film TTL to at least the F6. - Is there a non-Nikon unit that would be an alternative to the SB-900 which offers film TTL? E.g: Metz. - Does anyone have any experience with either the SB-900 OR SB-800 with a film SLR, in particular the FM2 or F6? - Is it worth me considering the SB-800 instead despite the inferior menu system? Going on the reviews I have read at least... Any constructive input or links to articles would be greatly appreciated! Thanks!
