When it was invented in 1840, the Petzval lens revolutionized photography thanks to its f/3.6 aperture. It's legendary for producing images with super sharp centers and unique backgrounds with a whirly bokeh -- as such it's particularly well suited for shooting portraits. Most Petzval lenses today are defective because of age and not optimized for modern cameras, so Lomography set out to reinvent the lens for the 21st century. The company just launched a Kickstarter campaign to bring the Petzval lens back for $300 -- it's teaming up with Zenit to manufacture high-quality lenses for analog and digital SLRs with Nikon F and Canon EF mounts. Lomography's Petzval lens is made of brass, features a gear rack focusing mechanism and comes with a Waterhouse aperture set (f/2.2, f/4, f/5.6, f/8, f/11 and f/16). Are you as intrigued as we are?
