I'm looking at the Canon 100-400mm lens as well, or the Canon 70-200mm f2.8 IS II with the teleconverter. As the cost is an issue, I thinking the Canon 100-400 might be the way to go as I can get it almost $1000 AUD cheaper than the 70-200mm. (not including the extender). If anyone has any thoughts on the two lenses, that would be greatly appreciated. The lens will be mainly used for my kids outdoor sports (Cricket and Aussie Rules football) where there will be plenty of light.
