I'm not sure I understand. Could you please elaborate? In what situations would you use a built-in flash to solve a low light problem, and can you describe in which way you would use it? Curious to know more about this - I recently bought a X100VI, which includes a built-in flash, and I was wondering what to do with it
Simple answer, I would use it when I didn't have enough light. It gives an old time candid look that is fine with me. Times I would use, inside candid shots, food shots when I am out on the town, portraits when I want to darken the background, and highlight the user. The leaf shutter makes the built in flash far more useful than a typical curtain shutter.
As far as your x100vi just play with the flash. Turn it on in daylight, in high DR situations, in pitch dark, and see what it can do. You will come away with ideas.
Are you also talking about a built-in flash trigger? I'm not familiar with this kind of system; all the lighting systems I've used worked with a dedicated flash trigger connected to the hotshoe. Could you please describe the kind of system you're referring to? And what kind of lighting would you / could you use with this kind of trigger ? (a traditional lighting set, including at least one softbox, is considerably bigger and heavier than a tripod...)
Yes a built in radio trigger, that could be configured from the camera's menu. My initial used would be for a hand held flash, but I would want one that could control several lights via radio. My Sony allows for configuring the lights within the camera menu but you need at least one flash/remote to manage it from the camera. Having that functionality built in would be incredibly cool/useful.
