Just playing around with the Nikon D3S (just arrived!), a 50mm 1.4, and listening to Rachmanioff plays Rachmanioff. The video is kind of choppy with a weird square in the middle — not sure why yet. I didn’t record it at highest quality. It also serves as a mini-tour of my office.
The rotor noise is the lens when I change the focus, I forgot to turn it off of auto-focus mode so it was louder than it needed to be. All sound is coming from the built-in mic.
