Canon Lens

I am very excited. I purchased one of the great birding lenses, a Canon 400mm f5.6L USM, which many people use, hand held, in the wild, to get some remarkable bird photos.  I can't wait to try in in Newfoundland, where there are so many petrels, shearwaters (Manx included), and puffins.  I've talked to a number of people who have been, and they are rapturous about it.  Imagine seeing icebergs the size of battleships floating by, and whales everywhere.  ahhh.
