I would also recommend getting the electronic viewfinder eyepiece for it too, the screen is sometimes difficult to see in bright light and you will certainly have that in Antarctica especially reflecting off the ice. No matter what camera you decide on I would also highly recommend getting some knee pads, they don't have to be fancy construction worker ones, I got lightweight foam ones for $4.99 at Menard's, the beaches are rocky & poopy, your knees will thank you when you get down to penguin level. Have a great trip!
