Zeiss Batis 85mm F1.8 lens... swirley!!!

The bokeh in general looked very smooth. As you can see some of my images below. Just when I started shooting in the woods, maybe when some trees were just exactly in the right location, the swirly appeared. It's not bad. I personally like swirly. It gives lens character. In my second image, the swirly disappeared.

First image was shot at F2 (the swirly one, pretty much no edits except adjusted exposure and resized) and second image was shot at F1.8 on a Sony A7.
