My macro bottle (Rear) I have adapters on order that will allow me to mount this end of the lens:

1. Directly onto my Nikon body F mount using a 58mm thread to Nikon F mount adapter.

2, Onto the front of my Nikon 55-300 mm lens using a 58/58mm coupling adapter.

For the time being, I have to hand-hold the lens in place (not very convenient, especially if you have les than 3 hands!).
