f4 for zooms plus a few primes vs f2.8

[Daniel Browning]

Thinking of buying the 24-105mm f4 plus a couple of primes (85mm and 135mm maybe).

Great idea! []

Is 2.8 going to be fast enough for that kind of indoor shooting?

Probably not. It depends on the venue lighting and shutter speed needed to stop action. The venues that I frequent are quite dim, and they require ISO 12,800 for f/4 @ 1/500. An f/1.8 lens brings me down to a much nicer ISO 2500 for 1/500.


I suggest going for the primes.
