This cheap lens makes square bokeh thanks to its aperture

Why only have round bokeh, when you can get it all sorts of shapes? You can achieve shaped bokeh by cutting a shape in black paper and placing it on the lens. Or if you’re too lazy or not really precise, you can even buy premade shapes. But what if I told you there’s a way to achieve square bokeh with nothing but a lens? Mathieu Stern presents you with a cheap lens that has a square aperture, so it creates super-interesting square bokeh.

Mathieu uses an enlarging lens from Schneider: Componar 75mm f/4.5. He adapts it to his mirrorless camera using M39 to M42 ring and adds M42 focusing helicoid. The lens costs from $30 to $50, from what I saw online. The ring and the adapter are under $40 together, so for the maximum of $90, you get quite a unique lens. It doesn’t only create square bokeh, but it’s also fairly sharp. Take a look at some sample images:

If you’re into playing with lenses, this one is quite affordable, yet really unique and good quality. So I believe it’s a good recommendation if you want to add something new to your photos.
