The HCR works just fine for outdoor shooting. I shoot with two SONY hd's. HDR-HC7 and a professional one.
I shoot extreme motocross sometimes, and the best thing about the HC7 is that it's light weight and I can follow their flips easier. I also shoot live footage of musicians, and I love the lightweight, non intrusiveness HC7. When I carry the professional camcorder, it's heavier and the musicians tend to stiffen up because they can't forget I'm there.
The only differences I find is that when I use a wireless lapel mic, it is dedicated sound thru it on the professional one whereas on the HC7, it picks up the person wearing it AND everything it would normally pick up. My voice behind the camera is the same db as the subject. So for that, I love the professional.
