It should … we have been going to Antarctica with cameras for decades.
Call Sea World's PR department in San Diego and ask to talk to one of the "bird people" there and then ask them how they protect their cameras when they are doing penguin censuses.
We used to use an external battery that was right next to our bodies (under layers of clothing) to keep them warm (they do not perform well when cold). There is also a technique for keeping the camera lens in a "cold locker" between uses, only bringing in the film (or memory card) with the battery between shoots.
I don't have enough knowledge about camera lens. I just bought a new canon camera EOS 50D. I am also planning to buy zoom lens but I have no idea what is the best lens for EOS 50D. Your recommendation is highly appreciated. Thank you.
For the 50D you will need a 'good' lens if you want excellent image quality. A cheap telephoto lens is not a good idea for a camera like this, so don't even think about getting a budget one that only costs a couple of hundred dollars or so, because it won't deliver on image quality and will not be good enough for lower lighting. One with a wider (faster) aperture of f/2.8 is an excellent choice.
From the Canon lens/camera review site below (of the 50D)…
"Because the quality of the lens makes a big difference in the image quality delivered by a DSLR – especially one with the resolution of the 50D, I recommend buying (now or later), one of the better Canon general purpose lenses available. At this review date, the Canon EF-S 17-55mm f/2.8 IS USM Lens is my most-recommended 1.6x lens with the Canon EF 24-105mm f/4 L IS USM Lens and the Canon EF 24-70mm f/2.8 L USM Lens being excellent alternatives."
Another excellent lens with a longer starting focal length is the EF 70-200mm f/2.8 L, with or without IS or the f/4 version with or without IS.
