Gah! Since upgrading to the Canon 180mm f/3.5 L Macro I need a 72mm adaptor to use the MT24-EX. I now find no-one has stock anywhere in the Uk or HK! Some have had it on back order since April and still not received stock Anyone know of any little shops around that might have one, at this point price is getting to be irrelevant. I don't want a £600 flash system [or a £1k lense] to be sat idle because of a £30 part Will be heading out this weekend to try the new macro but will miss the lighting from the MT Don't you just hate stock shortages, you would think the MT would come with both adaptors too at that price!
