The German company Rösch Feinmechanik are ready to design and build a tripod collar for the M.Zuiko 75-300 if they get 20 oders at least. it will cost around €80. Come on, guys, let's bombard them with orders! And it would be great if anybody who ordered would leave a short message here. So we will know if and when there is a chance to get our tripod mount ring.
