Photographer Mathieu Stern has built an admirable collection of rare, weird, super-cheap and DIY lenses so far. With his latest finding, he kinda brought all of this together. He laid his hands on a Cinestar 75mm f/1.9, a cinema projector lens. After making his own adapter, he used it on a Sony a7 III and tested it in a video. If you are a swirly bokeh fan, you’re gonna love it.
