I use the the wide version of this camera for street work. The 55mm lens is comparable to a 28mm in 35mm terms, but it has the beautiful, limited depth of field typical of 50mm lenses. Great shift from in to out of focus, very gentle and painterly. It's a superb camera given enough light. Typically when I want to use it around dusk I need to reach for some Delta 3200, which I tend to push to 1600 (I rate this film somewhere between 800-1250).
I've gotten some flare with it when shooting toward the sun, so you will want to pick up a hood for it.
