Plena?

A teaser of a new up-and coming lens.

135/1/8 with the perfectly smooth and circular bokeh?

[bressong]

guess new Z135/1.8 is extremely sharp, high resolution, low distortion, low CA
but,big, heavy, expensive

since I had the Sigma 135/1.8 art, I already had no more optical performance desire on 135/1.8, but the eye-tracking focus

piano - piano! I feel like Nikon have made too many offers lately that I cannot refuse

Plana? Plena! Opticus plenum

My bad!  Plena.  Thank you for the note!

Yeah, SIGMA 135/1.8 looks nice.  Apparently it is very well designed even without the software correction.

Daniel, sorry for your extra-expense.

I wonder if the knurled ring right below the "Plena" logo would be the defocus control like the ones on AF DC Nikkors 135 and 105?

As for me - new 105/1.2.  135 is flatting faces too much.  LZ

[Roland Vink]

105/1.2 would require a 95mm filter ... the lens previewed doesn't look that big. I'd say it is more likely to be the 135/1.8 that has been on the roadmap for some time.

The roadmap is currently showing outlines of only two new lenses, most likely a 135/1.8 and 35/1.2. Nikon haven't added any new lenses to the roadmap for some time so they may be abandoning it now they have a fairly complete range of lenses. So we might start seeing new lenses which were never on the roadmap such as a 104/1.4 - the lens shown in the preview looks a bit short for a fast 135mm lens?

[MILLIREHM]

A 135 mm f/1,8 with some sort of (advanced?) DC would be very interesting. I am sure Nikon will bring more Z lenses but not with the same pace they did since the coming out of Z-Mount. We might see Tilt/Shift lenses in the future.
Regarding Plena I still got no Idea why Nikon chose this name (although I got Latin teaching in School some decades ago)

[MEPER]

Is Plena supposed to be above S-line?

[MILLIREHM]

Is Plena supposed to be above S-line?

Who knows
But I guess not - otherwise the 400 and 600 mm TC lenses would be Plena as well. I think it is more dedicated to a unique lens or little set of lenses (maybe 135 and 105 mm?)

[MEPER]

I think the S-line lenses are already quite special.
That said I have only one so far. The 50/1.8. I have never had a normal lens with that wide open performance.
I was surprised with a portrait where I could see the interior of my living room in the eye. It is a head and shoulder portrait at f/1.8.
Non of my old 50mm Nikkors could do that. Maybe the 58/1.2 noct could come close at 1.8......who knows.....
So for me this 50/1.8 is my Plena lens :-)    ......maybe I have got a very good sample. I hope so......
The next is if I have hit 100% sharpness at eye or a little more sharpness could be achieved.

But let us see what this Plena is for a lens.......probably another price level than the 50/1.8.

I suspect Plena is short for plenary such as a plenary session at a meeting which is intended for everyone to attend. The e may have more than one pronunciation. I (US English) would the same as in the word plenty and cent which seems different from the vid which was a bit hard to hear.

[Erik Lund]

My first thought was that it was quite impressive they did a local promotion video,,,   
Well I soon found out you all have to live with that Copenhagen was selected to shoot it in   
If the out of focus highlights are for real it's quite the lens for sure! Very even neutral Bokeh.
