Since I only occasionally and rather spontaneously do macro shots, I decided for this intermediate rings instead of an expensive lens. For me a good decision. However, the autofocus works for me only partially or not at all even with only an intermediate ring (Canon 600D) and the edges are blurred. But for me as an amateur photographer and only "occasionally macro photo" I am satisfied. The Verarbeiung is okay, everything makes a strong impression. Desirable an instruction manual in German would have been, but it can go wrong is actually not. Conclusion:. For from time to time macro pictures really fine, but can not replace a lens
