After well nigh 7 years shooting with EX1/EX1R, only recently discovered the joys of a metal reinforced wrist brace. One of those velcro and neoprene ones with a bar down the palm to the forearm...

It's very comfortable and didn't stop doing high and low shots. I remember 'getting used to it' when they first came out, but a wrist injury and time with other cameras seems to have weakened 'that muscle' used by EX1s. Will probably work just as well for PMW200 & 300.

LOL - will keep it in the camera bag.
