I think that you'll do well with the 70-200 f/4. I've used the IS version (with IS off) for weddings (both with and without flash) and it's excellent. Much lighter than the 2.8, which I also have used.


Look at the varied opinions on this lens: Keith B did portraits with it, but couldn't wait to get rid of his. Yet, Roger demonstrated how excellent this lens is for portraits.


Can you see how these opposing views might make people go crazy???
