How to tell whether I need 70-200mm with IS or not, how much does IS help.
Does the pic quality has any difference compare with these two and the others two f4 family

When u want to shoot with hand-held at low light areas without flash...
Rule of thumb is 1/focal-length shutter speed.
Let's say 100mm should try to achieve 1/100 shutter speed to prevent too much blur.
But with IS, one can achieve slower shutter with hand-held example 1/50 at 100mm.

I own the IS one but never try before w/o IS.
Only one comment, it's heavy for weak arms and small hands.

Mine is 70-200mm w/o IS. IS is a nice feature but at extra $$$ and drains your battery too, so I usually shoot multiply shots and pick the best photos from the lot.
