There is a new MS Optics Petz 57mm f/2 FMC lens for Leica M-mount by Miyazaki San. This is a classic Petzval style lens with a classic bokeh (4 lenses in 4 groups). Here are the details:

History

The Petzval portrait lens was developed in 1840 by Petzval and Voigtländer. With a maximum aperture of f3.6, it was 20 times brighter than Chevalier’s f11 lens of the same period. Both resolution and contrast were excellent from maximum aperture. Its weak points were field curvature and uncorrected astigmatism. The lens corresponded to about a 180mm – 200mm Leica mount telephoto lens. Besides that, it was commonly said that the lens was unusable because of its harsh swirly bokeh.
