The rings make a very solid impression, have front and rear metal terminals, the contact pins are spring-loaded and thus provide the contact between camera and Obkektiv sicher.Ob the body is made of metal or plastic, I can not determine. If plastic, then quality. The rings are faced inside. Striking: Square white approach marks for EFS lenses and red round neck markings for EF lenses the same rings spitting the original Canon extension tubes. The release buttons are the same. It only lacks a label (13,21,31 mm). I have the rings with the Canon 100-400mm L tried 4.5-5.6 and the Tamron 100-300mm 4-5.6 Macro. With two lenses and each 2 rings autofocus with 3 rings only works in good light. All in all: Prima intermediate rings at affordable prices.
