Whoops - Canon did it again! 😄
l_d_allan: Very nice.
Regarding reflections from the viewing area ... wonder if they would be able to have a camera mounted outside on an arm with pivoting device, and use tethering software to leave it out there for a while?
With some kind of joy-stick to control "aim"? Will a camera work in vacuum? I suppose you'd have to take ijnto account "decompression"? Cosmic radiation would be a concern? Grit / sand at thousands of mph?
IMO the biggest issues come from excessive temperatures, which oscillate between -150/+150 °C in the space around the ISS. On the Moon the cameras were sealed/shielded in special cases which protected the delicate electronics. The problem is that the surface of the station is so cluttered with all the parts that it wouldn't be easy to maintain an unobstructed view at certain point for long period of time. That's one of the reasons the Cupola was mounted on the Tranquility/Unity module. The other reason is what Dr. Pettit mentioned in the video - there is so little time to take a picture that he has to grab a camera and shoot. There's no time to do anything else. It's just much easier to observe/photograph from the inside of the ISS then having to remotely control one camera at a time using an external remote manipulator.
marike6: This new lens is so sexy, if it were a woman, I'd date it.
Yep, no lens is as sexy as my black swan (AKA the 70-200 2.8 VR I) ;-)
Well, looking at the price point, thinking what would this lens give me that my 70-200/2.8 VR (the first gen.) can't... well, nothing. I bought this baby (not new but never used!!) for $ 1550 with 2 high quality filters, tripod collar (of course) and what more - it is weather sealed and has 2.8 aperture. Well, the VR isn't the latest generation, but in reality I'm sometimes able to take pictures at 5,33 EV under so nothing big here too. Honestly, usually I take pictures of people with this lens so I can't use that slow shutter speeds anyway... OK, this lens will be somewhat smaller and lighter but that's it. Nothing spectacular. I was hoping for better offer from Nikon to be honest (at least with a collar and weather sealing).
Below is a link to a simple noise test. Nothing scientific, but interesting IMO that at 50 ISO images look visibly softer that at 100, dunno why... At 3200 noise is becoming clearly visible.http://nikonclub.cz/clanek/nikon-d600-test-sumu-vysledky-vytecne
