18-55mm AL WR weird effects

Hi all,
I noticed some strange effect on lights. Which are not noticeable while shooting at widest focal length.

Some of lights has some kind of aureole.
Halo? Flare? How should I call it? After short search in a web I couldn't find even similar, except sun or moon pictures, but those You can see even with naked eye..
For now I don't know if I like it, but its interesting why I'm getting it.

So far I am about sure its more related to focal length then F, but I need more testing (and it needs low light ).
Also, does anybody had similar effects?

Looks a bit like how my Pentax Q handles bright light, but yours actually looks really good!
Do you got any haze on one of the lens elements? I like the look anyway.

Will try this again at todays evening. I wouldn't count it on haze, because it wasn't visible throw viewfinder.
I should test it with some other lens (I got old m42 50mm). I also forgot to check via live view.
For now I'm interested if it lens or camera fault.
If its lens fault I may blame pure internal(?) coating.

p.s.
I guess I need to make some check list, what to do:
test Live view
test on other lens
try to catch it on video

"The degree of coma visibility . . . is significant"

ISO 6400 will make it more obvious.

so its the lens "feature" and I have to live with it or love it
I guess I like it.

tried to make video, but as it was one of my first time doing it, it sucks a bit, but coma is visible.

thanks for all who replied, or wanted to...
