I went from Canon’s HV20 now up to the Canon T2i and I am not looking back. Well maybe a little. Though there is a line in on the camera there is no audio out besides A/V cables and when ya plug those in the LCD on the back turns off. I use my Zoom H4 audio recorder for sound now and then run a line from that into my DSLR. Also another draw back and no smooth zooming anymore. I just don’t use shots that I am zooming on now. I used to love a nice plan with a zoom but now its just the Plan or glide using a home made glide track.
If ya have any other questions just ask. We had basically the same DV cam so I am sure you had the same questions I did when I switched.
