Back in the golden age of the SLR film camera, there was a marvelous supplier of odds-and-ends, bits, and accessories called the Spiratone Company in New York. They were often the first US importers (I think the Maksutov mirror lens fell in this class), they provided thingies of marvelous inventiveness like the Colorflow™ filters, and they also beat everyone else pretty regularly in the introduction of affordable lenses of special kinds and for special uses. One of these was a (purposely) soft focus lens called the Spiratone Portragon 100mm f/4 lens, especially to meet the 'classical' photographic need for flattering, not too sharp images.

A portrait of my favorite 'sitter' taken with the Portragon with a trifle of massaging for a 'sculptural look' That's all folks!
