Cheap ones Rob, lots on the web. I had one in a box which fitted the DP3, it worked fine. Not as cool looking but very practical. Just fold it back before the camera goes into the bag. I like the hood or any hood as I can slip the camera which is around my neck, inside my shirt, or jacket with a button done up to stop it swinging around, the hood is enough to keep the lens clear of anything.
