To prevent the shutter speed from getting too long, many cameras (Nikon, Canon, LEICA M9, etc.) allow setting of the slowest sync speed in a menu.
But I am only able to find either 1/60-1/250 or 30"-1/250 on my R6. No option to set the slow sync limit to say 1/8. Flash is 580EXII.
Please help. Thank you.
