Calumet Photographic in Edinburgh probably provided the worst purchasing experience I have ever had. No updates when promised, item was not delivered on delivery date given at purchase time. Constantly given wrong information, no return calls unless I chased this up with the store. Initially the delivery date was before Christmas but after being assured that this would happen I was informed that my lens would not be delivered until after the New Year. Finally the order was cancelled. This was frustrating as the lens was required for a trip abroad just after the New Year. I will never use Calumet Photographic again and will not recommend them to anyone.
