Call me a Luddite, but I think you can achieve that look with depth of field, super diffused & bounced light, and a high quality lens.
There are separate instruments for our hero’s hair light and key light. You can see the source in the upper left hand frame. The hair light is a narrower beam- notice that it does not touch the actors in the background- and it is harder focus than the key light.
The key light is super bright, but also super diffused, probably bounced. I would guess this is a single large Fresnel unit, illuminating both the fore and background, but there could be a separate unit at the same angle for the background.
My guess is an ND filter will be just as important as a soft focus filter. The exposure is precisely perfect.
Also, my T3i has a soft filter setting in menu options, I bet your camera does too.
