How Light is an 800mm Lens? Although...

I think he mistakenly confused the 600mm it is with an 800mm, it is still a cool video...

Very cool.....nice equipment as well. Nikon is the choice of NASA.

Awesome video, especially viewed full screen at 720p!

That's pretty awesome. I wonder what they use those types of massive lenses for onboard the ISS. I figure if they're taking satellite photos or something similar, they'd use a fixed camera onboard the station or something.

One use of those teles is photographing the shuttle's tiles for damage before she docks with the ISS.

Cool Video. My one thought that came during viewing was, how much those lenses cost here on earth. In NASA's budget just pennies. Way to go NASA with Nikon.
