This depends too I think... hm. Melvan and I just did an event coverage last saturday. Don't know about his shots, but I think he was using faster shutter speeds. For me, I used 1/80s, ISO 800, F4.5, FEC about -1.7 on a 24-85mm F3.5-4.5 throughout. I find that lens a cheap alternative to the 24-105L, like 20% the price, & good wide open. In anycase thats not my main point, the sad thing is that I lost quite a few spontaneous moments due to subject movement, not handshake. I didn't consider on that day that 1/80 might be too slow & didn't have time to review properly. =(
Anyway, care to share how do you usually use your settings? I was kinda struggling with finding the proper FEC that day.
