Panamoz are doing the mk4 for 615 ish if you don't mind an import.I'll have to have a hunt and a play when we get back. The Mk IV is just too expensive at £848 but I could just about justify the £519 (after cashback) of the III if/when the XFs die! BUT, there's also the Nikon P900 which I'm sure will drop from its current £499. I know it's not pocketable but that zoom range is still mighty tempting, IF the IQ is any good.
