Short and did my first photo shoot and am thrilled. To get such a good macro lens for this price is not possible! Works flawlessly with all lenses corresponding to the thread. Even a 24-70mm holds the ring without any problems. Runs slightly when screwing (threaded and bayonet were clean cut) Seat firmly and does not wobble. For fixed ring (the Rändellung Although handy but lacks leverage) I shoot with an object / bayonet cap on! Even works with intermediate rings! These I have used to increase the distance to the object! Who wants a taster photography in the macro here gets the most cost effective way at all!
