Q: 9. Will this work with Sony a6000?

A: The lens includes a universal spring tension mount suitable for 52mm to 67mm filter sizes. So, if your lens is of this size it should work. You press the extensions shown in the photo inward and place the ring inside the lip of the lens . Slowly release the springs and it will self center and hold the adapter and lens in place. If used with care you should have no problems with it moving, This is not as good as a true macro lens but, it can't be beat for the money, i am very satisfied with it for occasional macro use.
