This is likely incomplete.
Canon HF R series
Canon HF M series
Canon HF S series (some of them)
Kodak Zi8
Zoom Q3HD
Maybe a Sanyo Xacti
I *think* only the Canon HF S series (maybe the HF M series) and the Zoom Q3HD have manual audio control.
ALL have small lenses and single, small imaging chip so don't expect great low light performance. The HF S series will fair well, but nowhere near any of the 70mm or larger cams with a 3-chip array.
ALL the Canons record to very compressed AVCHD MTS files. Hope your computer can deal with them. The others - I think - record to MOV files... since we don't know what editor or computer you are using, we don't know if you can deal with any of these files.
Have you found any others?
