I have one of the aforementioned lenses.
When I go to twiddle the soft focus dial, I notice I can use the refocus control to bring the sbject back into focus.
When I dial in 0 soft focus and use the defocus control I seem to get a similar effect to using the previous method.
Can someone tell me that the soft focus control does something other than defocus the lens ?? Can't I do that with any old lens ?
Has someone inserted some lens elements out of a different lens ??
