I just got my hands on the FA manual. It says:"The FA offers fully automatic through-the-lens (TTL) control of the falsh exposure" Now it also mentions that this is available with Nikon dedicated flash units and lists the SB15, 16B and 18. Why won't it work with the SB28? After all, if it did, that would be what I call backwards compatibility.
Actually, I just looked in my Magic Lantern guide and the author states "....but also with my Nikon FA using the standard TTL autoflash mode."
I guess I answered my own question. Should have looked in the book first.

You are right.. My mistake.. (that happend when you are too tired when you write..)
Next is form SB-28's manual "Standard TTL Flash (FA,FE2,FG,...) You manually select a flash output level so that the main subject is correctly exposed regardless of the background brightness. This system is not designed to automatically provide a balance between flash and ambient light; it is limited to efficient operation in dim-light conditions and is not recommended for use in very bright lighting conditions. This system does not directly link the cameras's light meter and the SB-28's TTL sensor."
