I've been looking at the Sony TG1/TG3 or Sanyo DMX-HD700 for helmet cam use. Both are small enough to be attached to the side of a helmet.

Obviously, either camcorder would have to run with the viewfinder stowed. I can't find out if these camcorders will run with the viewfinder stowed. Anyone know if they will run with the viewfinder stowed?

Another thing to query is whether anyone with a CMOS camera has tried this. CMOS can act a little weird around mid-frequency vibrations i.e. internal combustion engines.

I don't know if this is a problem for either of the cameras you've mentioned, but worth checking up on.

Check these skydiver's experiments with making a helmet holder for the TG3.

As far as the viewfinder - just flip it round and flush to the camera body and turn off the backlight to save on power as in this picture

Thanks for the feedback. It's going to be used in a sailplane, so the enviornment is not nearly as hostile as in freefall or biking. It's possible I could work up some kind of strap mount to the side of my head.

At present, I'm using a Sony DSC-W90 cam in mpeg movie mode. It shoots 640x480 4:3 video in mpeg2 format, with about 40 minutes of video available with an 4GB flash. I mount it on top of the bill of a baseball cap. It works pretty well, but the anti-shake is not very effective, and of course the video quality leaves something to be desired.

Any feedback regarding the merits of the two cameras I mentioned will be appreciated. Clearly, the TG1/TG3 is the better camera, but there are price issues too.
