In early 2016 Leica unveiled the world's first ever full matte brass finish M limited edition camera kit created especially for The Hour Glass in Singapore (I missed to report that announcement here on the blog). The kit includes a brass Leica Summicron-M 1:2/35mm ASPH lens. Only 35 pieces will be produced worldwide. The price is/was $35,000 (all sold out already).
