To "run in dedicated mode" you must do two things to the flash: Set the film's ASA Select one of several apertures, depending on how far away your subject is. The camera will read this info from the flash, automatically set the speed to 1/60th, and the match the aperture with the one selected on the flash, regardless of the current settings on the camera. All this will happen *if the flash is ready* when you take the picture. If the flash is not ready, your camera will ignore it. Hence, you don't have to mess around with the camera's settings at all. I have a Vivitar 3500 dedicated flash for my Canon A-1, and it performs beautifully. The head has 3 zoom positions (for ~28mm, ~50mm, ~70mm lenses) and several positions for bouncing around (lightwise). -- Theodore Hope School of ICS, Georgia Institute of Technology, Atlanta GA 30332 CSNet: Hope @ GaTech ARPA: Hope.GaTech @ CSNet-Relay uucp: ...!{akgua,allegra,rlgvax,sb1,unmvax,ut-ngp,ut-sally}!gatech!Hope
