Rubbish huh? OK. Well, as we all know, that one stop from f/4 to f/2.8 means twice as much light, which of course can make all the difference when capturing moving subjects (which IS won't help). By your reckoning, all the people that have spent the nearly £900 more on the 70-200 f/2.8 IS II instead of just getting the f/4 IS version should have saved their money and braced themselves against a wall instead? Seeing as the OP says he doesn't shoot any one thing in particular, it's difficult to know what would be the best set up for him; I appreciate your opinions (based on your experience) re focal lengths, but mine (also based on experience) are just valid too in these circumstances. It's really up to the OP to further clarify his shooting preferences, or just up to him to get out there with a bunch of focal lengths and see which general range suits him
