Next Z lens launch

I'm wondering if the 100-400 will be an f/4...
If the silhouette on Nikon's roadmap is accurate, there is no way the promised 100-400mm can be an f/4 lens. The front element diameter would need to be much larger.
Agreed.

The front element for the 180-400 f4 is approximately 106 mm in a 128mm diameter lens. The 80-400 f5.6 at 400mm accepts a 77mm filter.
OK perhaps it not a fixed f/4 but I don't think the lens line-up image (where it show sillhouettes of upcoming lenses) is entirely to scale either.

It's also hard to judge filter size IMO from that image. I mean the 14-24 Z, which takes 112mm filters looks smaller than the 14-30 which only takes 82mm filters (yet the 14-30 looks about the same size in the image).

The Z-mount 14-24mm/f2.8 S does not directly take 112mm front filters over its front element. That lens comes with a two-stage lens hood, which of course widens up rapidly to accommodate that super wide zoom. To use 112mm filters, you need to first mount the inner stage of the hood (which has front filter threads) onto the 14-24 and then mount the 112mm filter over the lens hood. That is why the front of that lens itself is much smaller than 112mm.

The 14-30mm/f4 S has front filter threads that directly accept 82mm filters. Its hood goes outside of the filter in the conventional manner.

Last year Nikon registered a patent for four Phase-Fresnel telephoto primes: 400 f/4.7, 400 f/4.2, 300 f/4 and 500 f/5.7

These were mentioned on NR a few months back, and they are possibly for Z-mount see http://disq.us/p/2cj9ce7
I’m all for more Phase-Fresnel lenses. I absolutely love my 300mm F4 PF, and the weight to tele it offers. I was hoping for a 500mm f4 PF though as a 500mm f5.6 really isn’t that different to a 300mm f4 with a teleconverter.

It all looks pretty much to scale to me. The diameter of the mount end of all the lenses in the graphic (including the future lens silhouettes) measures the same.

The mount end would need to be to scale, but I'm referring to the lenses overall. They're likely close to proportional of what they will be in reality.

Exactly. So it's easy to see that the front diameter of the 100-400mm silhouette is about the same size as the 70-200mm - which is much too narrow to support an f/4 aperture.

After looking, I guess Canon's was not an f/4 anyway (maybe I was thinking of their 70-200...)./ Either way, I wonder how it would stack up to other lenses in its class (such as the 200-500.... biut I'm going to guess it will probably beat the existing Tamron 100-400 and Sigma 100-400 in terms of sharpness and AF for sure if these long telephotos are anything like Nikon's other Z glass.

Either way, I wish they would announce it, even if we're still a year away from shipping (as I'm in the market for something like that).

While patents are a source of possible future products - not all patents go into final production.

The next launch could be around the 25th of this month at the virtual trade exhibition in Japan - and the black outline from the current road map size seem to be a Z 400 f2.8 Z and 600mm f4 size.

Even so I make it 4 of the Z mount lenses released so far have not been on a Nikon Road Map.

It would be great if Nikon would introduce lighter weight supertele lenses...

Right now:

Canon 400/2.8 weight 2840 gram, Nikon 3800 gram

Canon 600/4.0 weight 3050 gram, Nikon 3810 gram
 
It would not be correct to say where I received this information, but I learned from a reliable source that Nikon is not asleep and that it will release about 10 new products on the market this year: Lenses and Cameras.
I received an assurance that this would happen and that there was no need to worry.
The information is certainly accurate but at the moment it doesn’t help me at all.
 
I have seen the latest figures on lens and camera sales. This is not really motivetibg. Together with the Covid19 crisis photo companies have to think twice when to invest into new peoducts...

I hope Nikon ia able to deliver some new lenses this year.

We already know the lenses already on the Road Map - including 2 new long teles - and that Nikon have said they are working on new ML bodies.

A minimum of 7 new items this year is in line with what Nikon are implying they will deliver.

Nikon has gone very quiet, with 5 months since the last Nikon announcement (the 50mm f1.2) and 2 trade shows - and prolonged new product silence.
