Better to have the wider aperture non IS or IS lens with narrower aperture?

For instance, 70-200 f/4 IS or 70-200 f/2.8 non IS? Most of the use would primarily be outdoors. Isn't it true if your shooting outdoors in good light the IS doesn't really help a lot or am I mistaken?

IS won't freeze action. 2.8 will

EDIT: Not to say /4 won't stop the action but you get an additional stop of light by going the 2.8

Can you still hold your camera O.K. after a couple of pints of beer? Then go for the f/2.8 .

IS could buy you 3 stops of shutter speed versus just the one stop gained by f4 to f2.8. In addition, the IS helps you frame the shot as the image won't be jumping around as much in the viewfinder. However, if you need shutter speed to freeze action, then IS won't help you (except for panning in the newer versions of Canon's IS).

Would you use a monopod?

Hand holding is pretty difficult with the 70-200/2.8 without a tripod or monopod. Im not exactly weak and didn't believe the whole "70-200/2.8 is heavy" and after a trip to the zoo i realized that **** is heavy after 2 hours let alone 5. my hands were sore driving back home 2 hours away.

the /4 IS is 27 oz
while the /2.8 is 46 oz

It might not seem like much but for carrying around, i'd take the /4 IS. If i were to do sports and not move around or have a monopod then the /2.8 definitely seems like the way to go.


Note: I only owned the 70-200/2.8 but i now own the 135 L and that weighs 26.5 oz and i could carry that thing for a week with no issue.
