As long as the shutter speed is at the synch point or below, the amount of light will always be the same at a given lens opening. This is because the flash duration is always shorter than the shutter speed, usually 1/600 sec to 1/1000 or less. In fact the shutter could be set at "B", and the amount of light reaching the film would not be greater than at 1/4 sec etc. Joe Codispoti - ----- Original Message ----- From: "Albert Wang" <leica_phile@hotmail.com> To: <leica-users@mejac.palo-alto.ca.us> Sent: Tuesday, March 12, 2002 9:29 AM Subject: [Leica] How can I use a non-TTL flash on shutter speeds less than the flash sync speed? > Hi everyone, > > A minor question: which settings for the aperture should I use on a M3 if I > want to shoot at shutter speeds less than the 1/50 flash sync speed.
