The RH-A77 would be almost worthless for physical protection - it's a flimsy rubber hood that can be compressed to get it out of the way, but which would also bend out of the way in even the smallest impact. Perhaps the plastic threaded mounting ring might offer a bit of protection to the lens's own filter threads... Fred
