I have been making videos for a while now and am constantly amazed at the progression of the technology. Here are three HD cameras in the order I got them.
Canon AH-X1- $3500
A pro quality rig with all the bells and whistles. JD Johannes was jealous when he saw it.
Canon HF-100- $700
Still shoots full 1080i HD and records onto a flash card so no tapes needed. I can't see any difference in video quality from the pro rig. Also has an external mic jack so I get excellent sound.
Canon Powershot SD 780- $170
The latest toy. Records 720p HD and looks pretty darn good. No mic jack so the sound is less than stellar, but I can carry it everywhere. And it shoots 12 megapixel stills.
Here is a link to a video I shot with it posted over at Ace's place as it is kinda mean to our Narcissist in Chief.
