I'm a high school student extremely interested in video and film as a career. I've been participating in film festivals and even made the move to Mac to better my videos. Now I have a Sony DCR-HC90 and have had it for a year or two. Everything works fine and I have no complaints except for some pro features that its lacking. I'd love manual focus wheel, progressive scan, even 60 fps mode for slo-mo. Do you think a move to a GL2 is good enough? Will it make an image difference?
