Filmmaker Tim Irwin offers this handcrafted 90mm prime lens, The Simple 90, made with all 3D printed parts (except for the glass lenses, screws, and mounting plate). With its dreamy, soft-focus edges and sharp center, this lens invites artistic exploration. A throwback aperture system uses swappable plates (also 3D printed), and Irwin even shares the files so you can print your own custom blurs.
