>>3476788>Why do people act like flash sync is anything but a gimmickGimmick or not, it gives you results that you can't achieve otherwise with portable flashguns, let alone a built in flash.
A very typical example is fill flash in daylight with a moderate aperture (~f/5.6).
With most focal plane shutters you're limited at 1/125, so your aperture will be ~f/16 if you wanna use fill.
Practically that means you need a flash with a guide number of 2.5 times that of the fuji (which has a guide number of 9, so you're looking at ~GN22) to even be able to use fill flash with the same effectiveness, even if you disregard the different look due to different aperture. There's not a single camera with a built-in flash that powerful, so you're immediately comparing a compact pointy and shoot vs camera+external flash, even to be able to use fill on bright light.
What if you wanna bokeh-whore at f/2 with fill in bright sun? Well, on the fuji you'd use a 3-stop ND (cause you're already at f/5.6 and 1/1000). On another camera, you'd need a 6-stop ND, i.e. 3 stops darker. That would require again 2.5times higher GN number on your flash. If you used an external flash (speedlight, yongnuo) at half power on the fuji, you'd need a fucking alienbee on the other cam to get adequate power at half power.
You see the difference? The most simple example of that is, you turn on the integrated 3-stop ND on the fuji, and shoot at 1/1000 f/2 at full power. Or you get a 6-stop ND on the other cam, screw it on, mount a speedlight on the hotshoe, and get something similar. Which one is more practical?
And that's not even touch on the ""gimmick"" of overpowering the sun.
At 1/4000 sync vs 1/125, you're 5-stops apart. This means you need 4.5times the GN number on your flashlight to get the same effect on the sky. A speedlight is ~GN60, so you're looking at ~GN250 to replicate the effect. That's easily beyond speedlight power territory and well into big strobes + powerpack.
