Unlikely. This shot was taken at ~30 meters depth, ambient lighting (made worse by this being early morning, 6 AM), using a Sony A6300 (APS-C) with 16-50mm f/3.5-5.6 lens at 35mm f/5.6 (as wide as it would go at that FL), shutter speed 1/320, and auto ISO went all the way to 3200, resulting in evident noise:

1/1.7" f/2 is slightly slower than APS-C f/5.6, and if your ISO goes down four stops, the exposure time must compensate accordingly, going up to 1/40s, pretty much guaranteeing motion blur.
