I purchased a 2" GSO Barlow (sold under several names including TPO and Zhummel) that has a detachable lens cell. I wanted to go all threaded connections from scope to Barlow to camera. These M43 rings did the trick. I only needed one ring, but can use one of the others to vary the Barlow to sensor spacing to get a bit more or less than 2x.Well made and threads match other China made accessories, unlike some German Baader products. The gloss finish does appear to cause a problem with internal reflections.
