Thanks for the comparison!
I took my 16-35 F4 IS and 70-200 2.8 IS to Beijing last week and although I got those nice wide angle and telephoto shots of the Summer Palace I wanted, I found myself constantly missing the all-in-one reach of my 24-105.
I'm a video guy, so I prefer to have one lens that does it all. Still, good to know that I have a sharp 16-35 when I need it.
I also find that the IS on the 16-35 F4 is not as powerful as it is on the 24-105 when doing video. Anyone know why that is?
By the way, these are what they call "Uptown problems"
