After a relatively long wait, I got today my two clamps. This for my Macro and one for my 70-300 L IS. The clamp for the Macro is high-quality (aluminum and beautiful textured paint) and fits very well. The clamp is just right and the lens slips easily into the lead. It is lined with a lubricating layer, which prevents scratches on the lens. The change from portrait to landscape works very sensitively. The only complaint: The clamp does not protect against a complete unfolding. It is therefore advised when handling some caution. But I can absolutely get over with the price, so full marks awarded.
