The C-V lenses only allow close-ups. Magnification ranges of 1/3X to 1/5X.
The macro shots posted above are 3X life size.
FWIW, as I already said, I do not have the M mount Cosina lenses. Only the LTM ones. I use them with a NEX to LTM adapter and not the Hawk adapter.
I have lots of extension rings for any thread mount, including Leica threads.
