Medium Format Latest in Petzval Lens Resurgence
The swirly bokeh of fast lenses designed by Joseph Petzval in the mid-19th century is no longer solely available to fine art photographers using view cameras. In July, we profiled a Kickstarter campaign by Lomography to fund the creation of a brass Petzval for Nikon and Canon mounts. Now, a new campaign is hoping to fund the production of an F3.8 120mm lens for medium format cameras with a Pentacon Six and Hasselblad compatible mount.
The prototype Petvar lens was designed by Denys Ivanichek of Olympia, Washington based on the fast Joseph Petzval brass lenses that revolutionized 19th century portrait photography. Diamond Technologies created a fully functional, modern-looking lens and brought Ivanichek’s lens design schematics into the 21st century. The long focal length with the use of an adapter makes it possible to use the lens on a variety of other medium format cameras as well as 35mm cameras. The hope is to manufacture a small run of coated versions of the lens.
Old Petval meets new Petzval.
