HOLGA 110mm portrait lens
Don't you wish you had a full Holga outfit with wide and long lenses? I did! So I made a holga with a portrait lens. This is a single-element, plastic, 110mm lens. It is all the things that make Holgas great: Non-anachromatic, non-aspheric, non-astigmatic, and even more pincushioning than the Holga 60mm.
Built using a $2.49 magnifying glass from Walgreens (lovingly extracted from its housing with a 1" wood chisel) and about $15 of plumbing supplies (counting the stuff I bought "just in case" but never used). The Holga shutter had to be replaced since the aperture was much too small. I had purchased a cheapo Metax shutter on ebay a couple of months ago for $20, thinking I'd put it on a pinhole camera. This is a much better use! (The pinhole shutter will remain a strip of electrical tape.)
The image on the lower right shows a wax paper "ground glass" view (rather out-of-focus) of the image through the lens.
Most fun I've had on a camera mod since making my cigar box pinhole camera.
