The Carr II Photo Adapter screws into your beam splitter at one end and connects to your Nikon D70 /D100 camera lens at the other end. We recommend using the 60mm 2.8 AF Micro Nikkor lens. Using this lens, you will need the Universal Lens Mount, the Universal Heavy Duty Connector, and the Step-Down Ring. Click below on the accessories you want, then add them to your cart.
