Believe it or not with a locker full of glass I've never had a "standard" 50mm lens. Historically I've been a fan of zoom lenses. But with the crazy resolution and sharpness of the current fleet of bodies I find myself re-evaluating and drifting toward prime lenses in order to take full advantage of the sensor capabilities. Zooms with 3x or less range hold up well but Nikon's only current offering in "standard" range is the 24-70 which is pretty pricey and overdue for an update. So in the interim, I'm going prime time
