You always run the risk of busting the hot shoe. It's a lot easier to do than most people realize. The best configuration I've seen is to use a bottom plate and mount the device to the side of the camera.
Thanks, East Wind Photography. Plenty of good options now, a bottom plate as you suggest, a lightstand, tethering it to the tripod, a cage and the simple hot shoe adapter. I may just take it all along to a shop and see what works best.
I also tried mounting it to the bottom of the camera and found it would introduce noise into the camera's audio when wanting to use that track to sync the PCM audio.
Have you tried changing the wire to link the camera out on the Tascam and your mic slot in your camera? I have not had any noise issue so far.
It's also difficult to sync the start and stop of both devices at the same time. Still waiting for some smart engineer to develop a release that will start both recording at the same time.
There is a setting on the DR-60D that can automatically make a slate sound at the beginning and end (or just beginning if you want) of the recording. So I selected that option and then turn on the recording on the camera first before starting the Tascam recording. Works perfectly.
