Thats interesting! It could also be user error on my part...I'm no Fred
The coma testing results of your V2 is what is expected based on what Leica has published about the lens. Starting from V2 onward the lens should have good to excellent coma correction. I was unsure about the ASPH because I couldn't find any official documents, but you would assume Leica would only improve upon coma correction. The problem with assuming is it can make an "ass" out of "u" and "me". V1 was also unknown as there just isn't much information about it other than skip V1 and buy V2, which isn't helpful.
The winged coma on the V2 is unexpected. Either is not really a V2. There is a defect with that particular copy. It is a transition piece, or it is some franken lens or perhaps even it was serviced, and an element flipped or something of that sort.
