So I was wrong, it's not a mirror lens. I'm very surprised to see a kit lens producing this kind of bokeh.
By looking at your other pictures, I noticed that you have a somehow similar bokeh there, but with a different lens:
I am now wondering if this could be YOU doing something "unusual" instead of the lenses...
Wow Rina, I am disappointed that this was voted so low. I think the bokeh gave this a beautiful dreamy quality that was truly unique and artistic. For what it's worth, it is still a 10 in my book.
The entire shot just seems OOF with nothing that draws my eyes into the photo and I feel like I am looking for the subject. I do like the idea! Good luck in the challenge.
