Hello, I have a couple R6MKIIs that I've been using for portrait work. I usually shoot outdoors and with high speed sync. My shutter mode has been electronic 1st curtain. My shutter synchronization has been on second curtain. I shoot in manual mode and shoot faster shutter 1/2000, 1/3200 or so. According to the manual, if the shutter speed is 1/40 sec. or faster, first curtain will be applied automatically even if second-curtain is set. Should I just have the shutter on First-curtain? And the reason I'm thinking about this, is that I'm shooting an event indoors this weekend and will be using mostly on camera flash. My shutter speeds will be probably be under 1/250. Go with First-curtain shutter synchronization? Any other thoughts appreciated.
