The Sony A1 is a beast of a camera. He was likely shooting 30 frames per second. Even so, capturing a vapor trail of a bullet is quite astonishing, not impossible, but the timing is a miracle in itself....Posted by ThePythonicCow (here)
Is that "streak" showing the bullet itself, or is it showing a cloud of condensation formed by and left behind by the shock wave of the supersonic bullet?Posted by SilentFeathers (here)
As for this "Magic Bullet" captured whizzing by Trumps head, I find it odd he was at 1/8000sec, F/1.6, ISO-50, but, I don't really see it as being freak settings to be at.
I'd guess that clouds move slower than rifle bullets, so would be easier to capture on video.
ADDED: no normal professional camera can photograph a bullet in flight, a vapor trail is even highly unlikely, but not impossible.
One would need specialized high speed video/camera equipment that costs a fortune to actually capture a bullet in flight (done in a controlled setting).
