The method to connect SLR lenses to camera C for long-distance and magnified photography involves the relatively straightforward application of a C-mount to F-mount adapter.
Utilize the aforementioned adapter with Nikon’s telephoto lens (f =300mm) and connect it to DN3V-130.
The minimum distance is approximately 3 meters.
Observe the distant view at 3 meters, as depicted in the image below: 60mm×45mm.
