Trading the 70-200 4L for a 70-200 2.8L Good deal or go for 70-200 4L IS?

[Overkill]

I can get an 70-200 2.8L for a good price (800,00 euro).
Should i go for the deal and sell the 70-200 4L. Or wait
for a 70-200 4L Is?

if you dont mind the added wieght, and want the 2.8 app. go for it. Way i see it id rather have 2.8 and no IS and stop action, then F4 and IS and not stop action. what do you plan on shooting though? because if you dont think you would ever use 2.8, or dont want the added wieght then you might want to wait. cetainly neither decision would be a bad one

I used the 70-200 4L for quit a while....

I recently went to the zoo in Cloudy conditions and found the amount of pics that i could shoot (with no tripod) was very low. Lots of pictures were impos because the animals moved to fast or their was to little light to take the pic's without the Mono or Tripod!

well, IS will stop camera shake but it wont do a thing for stopping action for action you need to get a higher shutter speed, and therefore needed a lower appeture.

I will go for the 70-200 2.8! Thanks

Higher iso.

Expose properly and you'll avoid nasty grain. Again another case of high iso fear. Bump up the iso, carry a flash with you and light the place up.

I shot into the sun with a 1Ds classic, a 550ex and lit these people up from about 150 feet.

I have zero use for the 2.8. It weighs way too much to walk around with all day long and even at night I need DOF that 2.8 doesn't deliver. I use F4 glass all the time in very challenging light: Hard ugly light from a near equator sun, soggy limp light from monsoon like conditions.

F4 and bump the iso baby. If and when I get back to North america and away from a %33 import tax I'll grab an F4 IS.
