10 Beautiful Analog Black & White Portraits Shot with Petzval Lenses

As you have already known, Lomography successfully launched a crowdfunding campaign at Kickstarter to produce a new Petzval lens for analog and digital cameras. The new Petzval Lenses is designed and constructed by a team of optics specialists at the Zenit factory in Russia, together with Lomography.

According to Wikipedia, the original Petzval lens was developed in 1840 by Joseph Petzval. It consisted of two doublet lenses with an aperture stop in between. The front lens is well corrected for spherical aberrations but introduces coma. The second doublet corrects for this and the position of the stop corrects most of the astigmatism. However, this results in additional field curvature and vignetting. The total field of view is therefore restricted to about 30 degrees. An f-number of f/3.7 was achievable, which was considerably faster than other lenses of the time.

Photos shot with a Petzval lens are immediately recognizable for their super-sharp focus areas and wonderful swirly bokeh effect at the non-focused areas. Expect strong color saturation, artful vignettes and narrow depth of field. Here are some of sample analog portrait shots taken using Petzval lenses:
