I just got an Olympus 17mm f/1.8 a week ago. I haven't shot a lot of frames, but I noticed that in a few pictures I got this comet shaped flare in dark areas. Is my sample defective, or is this particular to this lens, or is this something that could happen with any other lens (flare)? I don't recall noticing this before with any other lens. I need to decide whether to return this lens or exchange it for another copy. I uploaded 2 pictures. They are crops so that you can see the coma like flare. Let me know if I should upload the entire frame. Thank you for any comments.
