I bought the same lens this week, and here's my first good picture:
I think the advantages of this unusual lens are apparent for this type of "intimate" portrait when you compare the previous image to a similar photo taken with a sharp lens (a 40mm limited):
I'm really enjoying the lens, although I'm beginning to regret getting the 85mm rather than the 35mm. The reason is that telephoto lenses offer nice soft backgrounds naturally. It seems that wide angle shots with soft focus would be the most surprising. Does anyone have any photos taken with the 35mm soft focus lens?
