Anil - are you concerned that Antarctic conditions might adversely affect the camera's operation? Other than that, I would assume any camera would work ....

For what it's worth, here's a recent field test of the iPhone 5s camera in Patagonia (not quite Antarctica, I know ....)

.... and if you want to see what the slow-motion video on an iPhone 5s is capable of, check this out -

.... all of which has nothing to do with Antarctica, I know, but it's pretty amazing what you can do with a phone camera these days - who needs a separate camera?

The book referred to above is called Antarctica on a Plate by Alexa Thomson. I no longer have the book but am pretty sure this is the right one. It's about an Australian woman who goes to Antarctica to work as a cook. She seemed quite unprepared for what was in front of her.
