Heliar 12mm II blur only on right edge of M8

[chounws]

I'm newbie for M digital, just came back to M8 after more than ten years with DSLR. Here is one of the place I do searching for information related.
I'm facing one problem with Voigtlander Heliar 12mm II ASPH and just finished the test to ensure that it is a problem.
I do find that on the right edge of the picture more blur than the left side and I believed that compared to most of picture of this lens posted over the internet is far better on the corner than mine.
please see the original size of the blurry pictures here...

any idea whether my copy of Heliar is bad or else would be very appreciated.

Two things come to mind:

1- is this an LTM/M39 lens? If so you might have a cheap adapter.

2- if this an M lens, you most likely have some optical decentering, or the mount isn't flush on the end of the lens. Either issue will require service.

Thanks kzphoto,
I have a M mount (new version) and I'm also believed that something wrong with the alignment, thank for your comment, I may have to go to the seller for claim.
