The Holga is a cheap medium format film camera that has achieved cult status for its inconsistent, truly unique photographs featuring blur, light leaks, vignetting, and distortion. Poor quality digital photos aren’t nearly as interesting and [Joachim Guanzon] wanted to achieve the Holga effect without using robotic Photoshop filters. He constructed this lens for his Canon 20D. The base is an EOS body cap with the center drilled out. A tube is constructed from a white film canister and the Holga lens is mounted inside. The tube length increases the usable distance of the camera and the white body lets some light leak in. A lens cap with a 3/16th inch hole is snapped over the top. The hole creates a vignette and since it isn’t permanently attached the pattern will be more random. Check out Joachim’s sample photos.
