I have finally found a camera bag that fits my needs (and my PMW-350K)! The Kata TCCT is a clever bag that converts from an airline regulation sized carry-on bag to a full size grab and go camera bag.

For a couple of years I have been using a conventional carry on case to take my broken down cameras on flights. This is OK, except that once at my destination and with the camera assembled I don’t have a bag for the camera and I have an empty case taking up valuable baggage space. I really could have done with the TCCT in Norway when the rental car company messed up and we only had a tiny car. For a full review of this excellent bag please CLICK HERE.
