A 3D printable Petzval style lens with mount options for Canon EF and Nikon F cameras. Uses a 42mm diameter 145mm focal length achromat for the front lens and a 31.7mm diameter 175mm focal length achromat for the rear. Together they are roughly 90mm and f/2.2.
The lens produces soft images with razor-thin depth of field and (in my opinion) fantastic bokeh. Field curvature causes sharpness to fall off away from the center of the image that, while terrible for landscape photos, creates a natural framing for portrait-type photos.
I have instructions for assembly as well as a walkthrough of how I designed this lens along with more test shots on my my website.
Thank you for your interest.
