I'm not sure if you're referring to the 70-200mm f/4L IS ($1200) or the 70-200mm f/4L non-IS ($650)? I would just like to point out the obvious, which is that the IS Version will give you an extra 4 stops, which will come in very handy, due to the long focal length as well as the actual physical length of this lens especially at dawn and dusk. So, consider that if you do forgo the f/2.8L IS II at least consider the 4 stop IS advantage of the f/4L.
I'm off to help prep my friends Sailboat for our race tomorrow.
I'll catch up with you guys you later!
