Chris, your SB-800 works very well with film cameras but Nikon's newer flash models, SB-700 and SB-900 and SB-whatever are only compatible with Nikon's DSLR cameras. All flashes up until SB-800 are good for FE2 or FA.
That sucks. I didn't realize the newer flashes took away the compatibility with the older cameras. My newest Nikon flash is the SB-800. I bought it for a digital camera I no longer own, and keep it in case I want to use it on my F4 (rarely...I almost never use flash).
