Ruined said:Except when you are forced to 12800+ ISO on the f/4 IS to compensate for less light entering the camera due to a maximum aperture of f/4 at a dim event, in which case the IQ of the 16-35 f/2.8L II at f/2.8-ISO 6400 will be far superior. f/4 lets in half the light of f/2.8, meaning you will be forced into motion-blur inducing shutter speeds or very high isos in dim light with moving subjects. IS can't help motion blur. I did see you qualify with your statements with "unless you need f/2.8," but the rest of your post seems to ignore these important issues.
How often do you need to do that? Doesn't superior IQ 99% of the time trump the other 1%?
