The Limbo Connection's photos with the keyword: tessarivy

In 2013 on a whim I bought a Carl Zeiss Jena f/2.8 50mm lens for £12. It has an M42 screw thread and initially I simply held it tight against the lens throat of a Nikon D50, with better results than expected. By the time I photographed this ivy I had graduated to using it on a Canon EOS 20D camera via an adapter. (M42 lenses are happier on Canons than Nikons. Yet the previous Canon FD mount lenses are problematic to use on the successor EOS cameras. Camera mounts are a bit bonkers). The Carl Zeiss Jena f/2.8 50mm lens is a simple Tessar arrangement of four elements originally designed by Paul Rudolph in 1902 while he worked at the Zeiss optical company. For the modest investment and the optical clarity I would recommend this lens.
