Caution: graphic Nikon images... :o

But how does one explain some of the pictures taken from the space station with a 1200mm lens?

My guess is they have a 1200mm lens.  Could be the Zoom-Nikkor 1200-1700mm f/5.6-8.0 ED-IF or the older  Zoom-Nikkor 360-1200 f/11 ED, or the Nikkor 1200 mm f/11 IF-ED Super Telephoto.  Or it could be a Russian made 1200mm, or a 1200mm mirror lens, or something custom.  Heck they could have a Canon 1200mm that had the mount shifted to Nikon.  They are NASA, when it cost $10,000 a pound to put something up there, they can probably have anything they want.

I saw this a few days ago, too.  Very interesting and great photos (and good background knowledge for when I'm next on the ISS...).  I hadn't really heard of Chris Hadfield until this, but I get the impression he must be a star in Canada.

Well anyone hear?
Apparently even Nikon F isn't good enough, NASA might be switching over to GoPro, wide enough lens and weighs nothing in comparison, and takes up barely any space, in space!

It's not a secret that NASA uses Nikon cameras and lenses (http://www.nikon.com/news/2009/1221_NASA-D3S_01.htm) after using Hasselblad cameras during the Apollo mission.
Could we reveal the reason?


very, very simple reason:

Hassy has a bigger camera body ( more easy to manipulate the settings in a space suit)

Nikon sensors have better DR than Canon.... and in space this performance is crucial.

I can't speak for NASA, but I can tell you that there are Canon cameras at the Canadian Space Agency..... and I know that they have at least one 800 F5.6 lens...... because it is on the other side of the room I am in!
The best camera is the one in your hands

NASA uses Nikon because nearly every MF telephoto NIKKOR lens can focus beyond infinity.
Happily ignoring the laws of physics and the rules of photography to create better pictures.

Yes it must be the DR. NASA has been awaiting that for years up until last year when Nikon introduced the D800...

Another reason to dislike nikons...  If you watch mythbusters, the cameras inside red light traffic cameras are nikons, so next time you get a ticket for running a red light, blame Nikon lol
Canon 5d III, Canon 24-105L, Canon 17-40L, Canon 70-200 F4L, Canon 100L 2.8, 430EX 2's and a lot of bumps along the road to get to where I am.

Well, factually speaking, DR is NOT the most important thing in space. NASA bought into Nikon a few years back because at the time Nikon was the king of HIGH ISO. You don't shoot the dark side of the Earth from space at ISO 100...you shoot it at ISO 6400, 12800 and at high shutter speeds to freeze the motion of 17,500mph! At High ISO, DR is physically limited. You lose about 1 stop DR per stop of ISO increase...you have only 7 or 8 stops at those high ISO, so the most important thing is the total electrons per pixel at maximum saturation. The higher the charge, the lower the noise.

Today, Canon rules the high ISO/SNR realm. By a relatively small margin compared to how much Nikon rules the low ISO/DR realm, but enough to give them an edge now. I believe the only reason NASA currently uses Nikon and has not changed to Canon is there really isn't any reason to. They are invested. They have the gear, have the lenses. Why change? They don't need the compelling features of the 1D X...it was built for sports, so it has an AF system and frame rate to match. I'd figure the most compelling Canon camera for NASA would be a 40-50mp FF monster with good ISO 25600 performance...which doesn't exist quite yet.
