the Pfocus | the 3D printable DIY single focus solution

thingiverse

This build requires many additional components and precise post-processing. This project is not recommended for beginners! Refer to the supplied .pdf manual for detailed instructions on how to assemble this device. The Pfocus DIY single focus solution based on a wideangle converter has some trade-offs like soft edges, CA or a slight widening effect, but also offers benefits such as minimal weight (around 335-350g), multiple mounting options, excellent wideangle coverage (more than a Rapido FVD-16a!) and close focus distance. For full tech specs, please refer to the .pdf manual. This build consists of five to six printed parts and is relatively easy to assemble, but requires precision for printing as well as post-processing of the parts. The Pfocus is designed to be somewhat modular, allowing it to be built with Canon- or Nikon-style focus direction, different front filter threads (77mm or 82mm recommended) and three different mounting options - 77mm male threads like a Rangerfinder, 75mm like a Rectilux Hardcore DNA or Rapido FVD-16a, or a universal mount fitting everything else. Additional components needed include screws and nuts, self-adhesive velours, step-down filters / empty filter, lube and a proper wideangle adapter: the Fujinon WCV-82SC.
