I need sample videos for the following cameras:
Canon XL2
Panasonic AG-DVX100B
AG-HVX200
AJ-HDC27H
The link shows the panasonic models I mentioned, can anyone tell me what the difference is cus all those numbers mean nothing to me,please?:D? but don't tell me which one is the best cus its obviously the most expensive one, but just tell me what is better in each model starting from the crappiest one. Thank You.
