What I wanted to do was to use TTL fill in flash with the R8 in aperture priority mode. I'm working with actors on stage where the lighting keeps changing. I need be at full aperture or near to get a high enough shutter speed with the ambient light. The problem is that as soon as the flash tells the camera it's charged and ready; in "A" mode the R8 fixes the shutter speed at 1/250 sec. I asked the people who should know and was told it couldn't be done. Well.....after much thought.... Set the mode to T (shutter priority) and set the shutter speed to the longest time of 16 seconds. You can now set the aperture and the camera will select a shutter speed to give a correct exposure for the ambient light. You can adjust the amount of flash fill (say -1 to -1 2/3 stops) on the SCA adapter or flash. This works as long as the chosen aperture and a shutter speed of 16 seconds will over expose and the shutter speed needed for correct exposure is not shorter than 1/250 sec. Why it works, is the camera detects that a shutter speed of 16 seconds will over expose, assumes the user has made an error and changes to an aperture priority mode in an attempt to get a correctly exposed picture. The only down side is a flashing T displayed in the viewfinder. This is because the mode switch is set to T and the lens is not stopped down fully.
