Thomas,
I also have this Hama M42 adapter. The vignetting causes the socket of into the
adapter incorporated lens. This
adapter is usable up to 200 mm focal length. Over 200 mm can happen vignetting. If You
don't need this lens
element in Your adapter, You can carefully remove this socket with help of a file. It
means, You can not put back
more this element. Otherwise this lens is worth nothing, destroyes the sharpness and
contrast highly.
I removed also this lens element becouse I use this adapter with an M42 below unit for
macro work, so I don't want
to focuse infinity.
With best,
