The only situation where this can be an issue is if you wanted to take a picture of, e.g., a flower, with the aperture wide open to blur the background, in bright sunlight. In such case you might need shutter speed shorter than 1/200 s, or your picture would be overexposed. This is when Auto FP (high-speed sync in Nikon talk) comes useful, as it allows for much shorter shutter speeds with a flash.
But I think D610 with R1 kit can do Auto FP. Can someone confirm this?
