From Photokina 2016, Nikon exhibits 2 models of super wide angle binos.

7x50 @ 10.7° (apparent 66.5°)and 10x50 @ 76.4°.

The models uses abbe-koenig prisms and ED lens. The optics are said to be flat-field and very well controlled.

For those cannot see the pictures, I'll copy the text explanations Nikon prints on the box of 7x50 model (from one of the pictures):

 

7x50 IF (tentative name)
Super-wide-field-of-view and high optical performance

 

Super-wide-field binoculars with an apparent field of view of 66.5°for 7X50 and 76.4°for 10x50
ED (Extra-low Dispersion) glass lenses that effectively compensate for chromatic aberrations to provide images of superior contrast and outstanding resolution
Abbe-Koenig prism, which is a total reflection Roof prism, is employed

From what I heard so far:

you should mention that the binocular exhibited was a prototype not for sale.

The prototype was visibly not a production bino; it was mentioned to a colleague in another forum that the weight was about 2500 g (7x50) and prices would exceed everything else in the market (several thousand euros).

So let's see where Nikon ends up with this (it looks / sounds they were just testing market interest in a new high performance instrument).

Yes, the word prototype is in my title.

Several thousand euro sounds a bit crazy...Makes me think of their 10x70 6.5° model 37 years ago.

This time let's just hope they will go into real production.

I'm actually very encouraged by Nikon's move. This is the first time when a company dare to make such an uncompromising hand held super wide angle binoculars after WWII. The market for this product is inevitably tiny and the profitability of which is at best questionable.

Those definitively look like a serious bit of kit! Those eyepieces are monstrous and probably account for the majority of the price. I am wondering if scaling up to 8x56 would make more sense in that price segment.

The eyepieces look like modified Nikon NAV HW :)

 

10x50, 9 degree TFOV looks very attractive.

Interesting.

 

I was just commenting to another CNer how within the lower end Aculon range most of the models were relatively wide except one or two.  One being the Aculon 7x50s with a miserable 6.5 degree FOV (compared to 9.3 degrees with the 7x35s).  Given that the A211 line uses aspherical elements, very clearly the Aculon 7x50s could have been wider and delivered decent performance.

 

Now I suspect that even in 2013 when they launched the Aculon line, they already had a different strategy in mind for a wide field 7x50 targeted at us astronomers.  I bet they'll be Prostar in price though.

 

Thanks for the link!

True, but they invested in eyepiece technology (NAV-SWs and NAV-HWs) and that market, in astronomical formats anyway, is even tinier.  I suspect this project leverages developments made in the NAV projects on the back end.

 

Now, how do we lure Nikon back into the worldwide astronomical refractor market.  :thinking:

 

Kudos for them investing in niche optics markets where others instead are retreating from/surrendering to the low end producers.

 

Color me interested.

Should not be too bad I think, with the use of AK prisms.

The photos clearly show that the eyepieces are closer together than the objectives.

On one of the pictures in the links above, an IPD scale is seen.

Unfortunately the resolution of those images is low, but I'm almost getting the impression the lower number starts with a 4 (which I wouldn't understand given how massive those eyepieces look).

Just for the sake of discussion, suppose these would retail at $3500. Who would buy a pair?

That's a fair price!

2 Nikon hw eyepiece already costs 2000.

And considering its workmanship is up to EDG standard which also costs 2000.

I doubt they are the actual NAV eyepieces as the largest one is 17.5 and that would make the objective lenses f2.8 which even for binoculars might be a little fast.

So what do the two apparently different AFOV mean? Does the ISO (International Organization of Standardization) have a diff. measure?

 

That seems...well....non-standard :)

 

Ultra Wide Binocular
7x50IF FOV 10.7deg AF 75deg (ISO66.6deg)
10x50IF FOV 9deg AF 90deg (ISO76.4deg)

Bigger prisms and eyepieces are needed to give the 7x50 the same wide view. It would be bigger than a 10x50.

Nikon is one of the few binocular mfgrs that use the ISO formula for calculating AFOV rather than the "simple" mag. x TFOV method that has been the norm for most.

 Now if I can only find out why the photo of an  arctic worker in hardhat, cordoned off in a small area with goats ,was doing in the same astro thread as these binocualrs:

Looks like the weight posted above @2500g, 88oz, 5.5lbs necessitates yet another proprietary adapter :(

A 9-degree 10X though, under the darkest skies, the views would be astounding.

Although doing it up at at 10x50 is a very smart plan.

Nope.

 

$2k to $2.5k, perhaps.  But more than that, nope.
