Or just go buy the TT Artisan one at £159 and that's Lumix's loss in terms of lens sales at least.
IMO, unless you want to shoot cropped video, in which case the Sigma 17-50mm f2.8 is a great choice, for stills, the 40mm f2 is a perfect match.
I didn't realise it was a limited edition and even if they gave away 1/2 of them, apparently still at least one available as it's listed as in stock on Panny's UK website at £1199 inc. matching Titty lens.
Might just pick one up to sell on to the Leica Sunday polishers...
