I may also post this in Editing software forum but I will ask here first. At the present I own a Sony CX550 camcorder witch is AVCHD and uses the .mts2 files. I also on own a Canon G12 which I use for Photos and sometimes video. I also own three different Canon EF zoon lens from old EOS cameras. I am beginning to do more event work for family and friends. Need more cameras to do multi camera angles. I know I will be purchasing either the Canon 60D or 7D for mostly Photos and some video work. I worry if can get color of the Sony to match the Canon gear in Post Production. Need suggestions on next camcorder.

Option1: Should I keep the Sony and purchase the ( Canon XA20 main camera ) and try to match color in Post with the rest of my Canon gear?

Option2: Or should I sell the Sony and purchase Canon Vixia HF G20?

Purchasing two XA20 is out of my budget.

I'll just tell you my experience. Working with AVCHD and trying to get the colors to match is just too much work for this level of work you mention. You may get colors close but they will never match exactly. I have tried matching my panasonic TM-900 to Canon and never get an exact match...and when you're cutting from a left side angle on one camera to a right side angle with a similar focal length the differences can still show through even after color correction. Sometimes I can get the skin tones to come close but then the background or wall will be slightly off. And when you already dealing with a low budget client, yet you want to put out your best work and use it in your portfolio, I just became a firm believer in using same Brand (preferably same model also) video cameras for multi-cam shoots.

Yeah, mixing different brand of camera's will always give you colors that are slightly off and very difficult to get exactly right, I have 2 sony cx730 and they match exactly but my xr500/520 already look different, eventhough they are sony as well, they are sharper which is a sharpness applied in camera and they have more contrast and saturation. You are best off with two the same type of camera's.
