Lensbaby just released a new 56mm f/1.6 soft focus lens in various 35mm mounts. $500-$600 depending on the barrel finish. Looks like it's either a meniscus lens or an achromat, but I didn't see any information about the design.

According to the old standard formula for portrait lenses of film length plus film width, that's 60mm for 35mm so this lens isn't really that far off, even though 35mm photogs have accustomed themselves to 90 or so.
