If you normally shoot bands or weddings then be ready to bump your ISO or slow your shutter speed (the widest it'll go is f4).

With the new FF cameras that have such good high ISO quality you might find F/4 is all you need anymore, and at the longer focal lengths you can still get pretty decent bokeh.

In most conditions, f/4 is wide enough to give me shutter speeds of 1/250 and better even at a conservative ISO; I was worried at first about not having f/2.8, but that has been a non-issue for my uses.

It's a sizeable lens, and makes my 6D fairly heavy, but the combination of being fast enough (f/4) when wide open, the very solid image stabilization, and the 6D's clean high-ISO performance make this a great party and indoor all-around lens, and the very useful zoom range is just icing on the cake

Newer cameras you can bump up your ISO easily.

In that case just bump up the ISO and use the terrific IS and you will produce fantastic indoor images.

Canon EF 24-70mm f/2.8L USM Standard Zoom Lens and seeing as how I do not shoot in low light (I bump up the ISO when needed

IS can be a real "image saver" so many times by allowing lower ISO's and slower shutter speeds.

I kind of regret not holding out a little longer cause I would have chose the white box

Upgraded from the Canon EF-S 18-135mm and the difference was incredible

(Note: it has an EF-S, not EF mount, so it's not compatible with the
