One of the ongoing mysteries on the Nikon rumor sites has been answered. And it comes in the form of the new NIKKOR Z 135mm f/1.8 S Plena.

When rumors of a new Nikon product with the word “plena” associated with it started to bubble up a few months ago, it was anybody’s guess what product the moniker would find itself attached to. Well, as it turns out, just as the word Noct brings to mind a very specific iconic lens within the Nikon ecosystem, the name Plena is meant to confer the same level of uniqueness to this new offering.

A bright prime, the NIKKOR Z 135mm f/1.8 S Plena seeks to take after its nickname, which, in Latin, means a state of space being completely full. The idea being that this lens may well become known for its light-gathering abilities, well-rounded bokeh, and clarity from edge to edge. Nikon has designed the lens specifically with edge-to-edge brightness in mind to provide what they say will be the ultimate in illumination across the frame.

The 11-blade diaphragm and large rear element help form a circular bokeh and something of a three-dimensional look to images. Combining its focal length with a maximum aperture of f/1.8, creating shallow depth of field with this lens should be a joy. Unlike the Noct, the Plena is autofocus. However, there is no VR built into the lens. There are 16 elements in 14 groups. And the lens comes in at a weight of 2.2 lbs or 995 grams.

The lens should be available in mid-October and comes in at $2,499.95, a similar price to other high-end Nikon professional primes, like the Z 50mm f/1.2 S or the excellent Z 85mm f/1.2 S. This should be a premium option for prime shooters in the market for this focal length.

What do you think? Would the Plena find a way into your kit?
