I am agonising over choosing between one of these two lens's.
I Like my wildlife, events, and also would do the odd portrait, with nearly everyting outside so F4 would be fine (besides can not afford F2.8 IS)
From the way too many reviews I have read, both are "great Lens's"
Is there anybody who has gone from one to the other, or own both and can give some "real life" reviews.
I will mention I would probably get the 1.4 x convertor if I got the 70-200.
Camera to be used on would be 7D.
Any help in deciding would be greatly appreciated.
