This weekend past I picked up my trusty GRD III to take with me on a trip, but as I picked it up I noticed the lens ring cover was missing, I thought oh it must be in the bag but no. I have hunted high and low but to no luck. So I emailed Ricoh who haven't replied re a replacement. Now what I need to know is does the GRD I / II lens ring cover fit the III as I can get hold of them quite easily? Thanks Ash
