There are a couple of schools of thought when it comes to the perfect portrait lens. An 85mm gives a flattering perspective and enables close-up upper body shots from a discrete shooting distance, while a 135mm gets even closer for frame-filling headshots. Either way, the lens needs to have a wide maximum aperture, to blow out the background into a pleasing blur, thus concentrating the viewer's gaze on the subject.
Until now, you'd have to decide between a lens like the Nikon Z 85mm f/1.8 S or the Nikon Z 135mm f/1.8 S Plena (a lens so special it gets its own unique designation). But if this new 85-135mm f/1.8-2.8 zoom lens that Nikon has patented makes it off the drawing board, then it could do the job of both, giving you two lenses in one.
