Im looking to start doing some automotive action event coverage and Im looking at a new camera. I started off looking at the new Canon XA20, but for the price compared to the new Canon HF G30, the only difference i could see was the microphone holder and handle on the XA20. Is there other differences between the two or for price wise the HF G30 just as good?
