I'm wondering if anyone has tried the 'Zing Designs' PVC camera cover for the FZ10.
You can see it here:
In particular, the 'Standard SLR Cover' which is available from B&H for $29.95. From the pictures, it looks like it might do the job of just protecting the camera from lumps and bruises.
I spoke to one of the people at the Panasonic booth at the recent PMA Show in Las Vegas. He knew of no plans for Panasonic to bring out a case especially made for the FZ10.
