I own and operate a small off-roading business. We do a lot of video advertising on YouTube as well as produce DVDs of our racing and riding. We are entering the world of video podcasting. Up until now we have shot all of the footage with a variety of 3 home video cameras. I now am looking to upgrade to a professional grade camera. I need a good camera with decent zoom capabilities and the ability to endure outdoor shooting. A good on camera mic is a must, a port for a remote mic would be a plus. I am looking at the Canon XL1, XL2,GL2 and the Sony FX1. I need to stay in the $1500 and below range. Any suggestions from you all?
