The first images of the Voigtlander VM-E Close Focus II have come out and it looks like any other solid M mount adapter. We should see this adapter soon at B&H Photo.
In addition to expanding the extension width of the proximity helicoid from the conventional 4.0 mm to 4.3 mm, the weight has been reduced by about 50 g compared to the conventional one by reviewing the internal structure. There are also differences in appearance, such as changing the knurling to a diamond pattern.
