Just acquired one of these with unknown Camera Adapter.
I am fully aware of the advantages / disadvantages of these particular genera of lenses but for $25 it's a new toy for the Nikon D 3300.
Having difficulty in tracking down what Camera it was off. Just spent 2 hours searching everywhere for a Makinon information re code on adapter. The Code is " CA " hopefully this can steer me in the right direction for an adapter the the Nikon F Mount. I presume that is what I am looking for as I haven't found anything to tell me otherwise.
Lens did have a few spider webs of fungus but was simple to pull apart and clean.
A few pics to help along the way.
Hope the pics aren't too big.
