Frustrating purchases Initially.
This adaptor is of good quality,fits the lenses well,but there are no instructions whatsoever on how to attach it to the lenses.It was initially a very frustrating purchases,as I could not figure out how to fit the lenses to the adaptor.Even You tube videos did not make it clear. I very nearly threw the adaptor away in frustration and anger.It was only after many days searching the internet that I found the answer on the Photo.net forums.Which is that,' The raised red index button on the outside of the lens must be aligned with the red dot on the flat circular plate on the back of the lens (i.e., the plate in which the various aperture levers are located). If these are not aligned on your lens, rotate the inner portion of the back of the lens counterclockwise while pushing in the chrome lens lock button. The back of the lens should click into position when the red index button and red dot line up.' Had I not found this information I would have thrown the adaptor away,and moved away from Canon lenses altogether.
