If you like swirly bokeh as much as I do, here’s a real treat. Kipronar 105mm f/1.9 is a cheap projector lens that will give you the most amazing bokeh for photos and videos. Mathieu Stern found one for only €20 (around $23) and in this video, he shows you what it can do.
I assume that the seller didn’t know exactly what they were selling, since this lens costs around $130-$140 online. But whatever was the case, Mathieu used a great opportunity to get it for a cheap price.
There are no focusing mechanism or aperture blades on the Kipronar 105mm f/1.9. So, Mathieu fitted the lens inside a helicoid ring adapter to make him able to focus. He also used an M65 to E-mount adapter so he could fit the lens onto a Sony A7III. In the video, you can check out some sample shots and see how freakin’ beautiful its bokeh is. I also found a few example photos on Flickr, and I think this lens works amazing for portraits both because of the bokeh and the background separation.
