Well-known
The 35mm RF lens I've found that gives the closest "classic" soft focus effect is the Nikkor 50/1.4, but only wide open. Even stopped halfway to F2, it becomes sharp. But that's how most of the large format soft focus lenses were controlled too - by the iris. Here are two shots I just took, one at 1.4, the other at 2.0. Again, SF is easier to see large, so here is a bigger copy at 1.4: http://www.flickr.com/photos/garrettsphotos/8652529174/sizes/h/in/photostream/
