Using the Quenox adapter with in-built lens for M42 to Nikon F-Mount with Mamiya SX AUTO lenses provides some interesting results. Both in colour saturation and bokeh.
In this video there are 3 sample pictures for each of the 28mm f 2.8 and the 105mm f 2.8 Mamiya SX Auto lenses.
I just wanted to show some samples, share my experience and explain the problems I had.
If anyone has additional information or experience on this combination please do add comments below to help others decide what might be interesting to try.
