Seriously, the overheating on the 550D is really, really annoying. Seems like every other shoot it overheats and I have to stop a shoot. Can't wait to get the C100 and shelf the 550 for my B Cam. /rant off
Ok, so I'm going to spring for the C100 to replace my HMC40 before the rebate expires in June. I think it will be a nice main cam for our commercial work and for weddings with the 550D as B Cam.
Anyhow, the lenses I have now are the Sigma 30mm 1.4, Tamron 24-70 2.8 VC, and the Canon 70-200 2.8...
