Hi all ! Have a particular problem posed to me by a friend about his F801s. Problem is this : He just bought a new SB 28 for use with his 801. What he notices is that, after shooting for like 15- 20 shots, with about 1 - 2 mins between shots, leisurely kind of shooting, the camera just "freezes". The LCD shows "fEE" . What is interesting is that the aperture ring is still set at f 22 and removing the lens and fixing the lens back doesn't help. Adjusting the aperture ring doesn't help either. The camera also doesn't clear even when either the camera or the flash unit or both are switched off and on again. What helps is to completely remove the flash unit form the hot shoe and attach it again. The display will clear and the camera starts working again. He noticed that this happens even with other non-dedicated flash units, not only the SB 28. Does anyone experience such a problem ? Is it due to the camera or the flash units ? Any suggestions appreciated ! Thanks.
