My friend has asked me to take pictures at an event he is hosting in some small performance venues in San Francisco (one is the Old First Church). I'll be taking photos pre/post concert as well. I've never done an event before (my friend knows that, he just wants pictures that look better than something from a P&S), and I have some concerns...
Do you think the Canon 55-250 will be capable enough to get some close-ups of the performance, without flash? I will most likely bring a tripod to assist with shooting as well. I'll also be using the Tamron 17-50 or the Nifty-Fifty for shots of people pre/post concert. I should be able to use my YN-465 as bounce flash. I do have an umbrella setup but I don't think that will be necessary.
I'm also contemplating swapping my T3i for a 60D (would be about $20 more after selling the T3i and kit lens) - would the shutter sound be obnoxious during a live performance? It's modern classical music, which is mostly going to be atonal or very angsty sounding, but I'm sure there will be quiet moments as well.
Thanks a lot!
