The problem with faster than f2.8 lenses for 'event' style work is that less dof than f2.8 is too limiting much of the time. In any given shooting situation there is a limit for the actual required dof, too often this is completely ignored in these threads.
Agree 100%. In simplest terms -- though an f/1.4 lens lets you get that shot, you often are handcuffed compositionally and *must* use f/1.4 to net that shot at (say) your highest acceptable ISO level. Good luck with that for anything other than shooting individuals.
So this is a less a need for an f/2.8 zoom as it is for an
IS prime. I've said this many times: providing your subject isn't moving, IS is
latitude for compositions in low light -- latitude to stop down if the composition demands it, and latitude to walk the ISO back down to earth when you don't.
The problem is, Canon has only put IS on the following 'more common FL' primes:
24 f/2.8
28 f/2.8
35 f/2
100 f/2.8L
We haven't seen a super sexy indoor event tool like a 50 f/1.4 IS, 85 f/1.8 IS, or 135 f/2L IS, but imagine what you could do with those in those tough circumstances.
But I'm OT. Apologies.
