Hope somebody here can help...
Looking at either the 70 200 F/2.8L or IS f/4.0L

Would like to know how much benefit the 2.8 will give when shooting low light I.e music festival at night etc..

My other lens only gets to f/3.5 so cant compare.

Are their any others in this field worth looking at?
Will be shooting with a 7d

There's a ton of info if you do some searching. This is a pretty common question.


Cheers,

You can shoot in 1/2 as much light with the 2.8. If you're shooting static objects ie, the speakers or fans at the festival then the f4/IS will wipe out that advantage, if your shooting people moving around, drummers, dancers and such I'd grab the 2.8.

I'd get the f4. Had a couple of 2.8 (non IS) and both were soft when wide open.

A sharp lens that is too slow for the intended purpose really isn't much use.

I personally prefer the f/4 IS due to its weight and size! And I use mine mainly outdoor for portraits, f/4 is more than enough for me!

If you really need the low light capability, I suggest to go for prime. F/2.8 sometimes is still not fast enough, especially for concert and bad lit environment, like a bar!

You don't hear that too often....Mine were both very sharp wide open.

It kind of depends on the situation. Say you are shooting people acting on a stage and have to use 200mm. Assuming the 1/fl * crop thumbrule, you need 1/320" to shoot with the 2.8 non IS to get no shake blur. However, you could shoot at 1/80" because the people are not moving around that fast. In this situation, the f4 IS would give you 1 stop advantage.

Now say you are shooting a basketball game indoors and need 1/500' to shoot the action, Here the 2.8 non Is is the clear winner.

My solution here is to go with the lightweight on camera option. I have the f4 IS and when I need a larger aperture, I go to the 85/1.8 and in the future, I will add a 135/2 for more reach.
