The Korsar 35mm is a super-vintage lens. Which has a pretty old look. The lens can mount to m4/3 and Sony-E, but will vegnette on Sony.
The lens doesn’t have a hard stop for close focus. Eventually, the front of the lens comes off. Which can create some impractical, in-camera effects. Here is a test video: https://vimeo.com/349162141
This lens should be experimented with for overly classic looks.
