New scope from Zeiss...
 
Coming soon, apparently a 95mm lens with large zoom range, teaser video here. Perhaps a new diascope to rival ATX/Kowa? Or just a bigger Gavia?

Thanks for that Daniel

Didn't see anything about the zoom range.

I thought Zeiss were bringing out 32mm SF's at the Birdfair...

jring Monday 7th August 2017 18:06

Hi,

the video is quite vague indeed - looks more like Gavia than Diascope with the helical focuser.

I think that it would be very strange if it is an expensive Gavia. Really hope they will release a worthy replacement to the diascope.

"The most powerful scope"? More than 75x mag? 95mm it seems, or 95x mag perhaps...

Helical focuser & zoom? Almost looks as if it has two "zoom" rings. Or is it a twist built-in teleconverter?

dwatsonbirder Monday 7th August 2017 20:38

Perhaps its a modular offering? In the video, it mentions "most powerful yet" so I'd anticipated at least 75x and maybe a 95mm objective? Not to get collective hopes up, but I heard that there has been a pre-production SF32 doing the rounds in the UK in the last month or so, but my source is not the most reliable.

It's about time for Zeiss to come up with a scope that can compete against the big Kowa and the Swarovski ATX, I'd say.

Looks like that, doesn't it? Focuser and built-in zoom, separate from the eyepice?

Now, that would be an interesting concept.

I just don't understand why Zeiss hasn't brought out a new 8x32 yet. OK, maybe they had to change a few things after working on the focuser of the (grey) SF, but surely it's about time for a new 8x32.

BTW, Leica also seems to be fast asleep. An 8x32 Noctivid would also be of interest to quite a few people, I reckon.

On the eye piece it says:
23-70x95 and 22-65x85

So there should be two different sized objectives/bodies.

The complete photo can be seen here:

https://www.zeiss.com/sports-optics/...-b-xl-1920.jpg

Image name is "victory-spotter-b-xl-1920.jpg" so it seems it's a top of the line scope. :t:

Eye piece lens looks like it has pretty large diameter, so eye relief will be probably very good.
Eye piece seems to be removable.
Body material looks a bit like CARBON FIBRE but possible it's just the rubber armoring...

henry link Tuesday 8th August 2017 12:40

It's odd that the zoom ratios for the two apertures are not quite the same. Maybe the magnifications are rounded to the closest whole number for one or both. For instance, if the 22x65x85 is really 21.5x65.4x85 that would make things about right.

This sure looks like another Kamakura product, maybe this time with enough value added at Wetzlar for a "Made in Germany" label. Compared to the Gavia I would hope for better color correction, lower spherical aberration and a clear aperture that matches the specified aperture.

jring Tuesday 8th August 2017 14:20

Hi,

so we have a 3x zoom range - it will be interesting what the FoV will be like - the wide angle zooms of the competition usually trade some zoom range for a wider FoV.
If we assume a 8-24mm zoom, this would make the 85mm version around 525mm or f6.2 and the 95mm version slightly faster around 555mm or f5.8. Are physical dimensions known already?

Regarding the two "focus" rings on the body - could that be a coarse and fine focus?

Joachim

Vespobuteo Tuesday 8th August 2017 14:57

Fine and coarse focus, didn't think about that one, but it's possible,
not sure if it's a good idea though, but at 70x and 95mm aperture it might be useful.

The naming indicates that it's a "Victory" series,
but it sure looks a bit like he Gavia, haven't found any possible 95mm kamakura clones though,
maybe it's a special design for Zeiss,
or is it related to the Meopta S2 HD?

Not made in Germany would be a disappointment...
Better optical quality than the Gavia
will definitely be needed, to make me interested...

One possibility is that the zoom (if it is a zoom) will fit on that Gavia as well.
Would explain the 85mm reference on the EP.

kabsetz Tuesday 8th August 2017 16:09

Henry,

The discrepancy (small at that) in the zoom ratios most likely does come from rounding of the numbers to the nearest or best looking full integral. In any case, decimals don't really matter when it comes to magnification factor. FOV figures would be interesting to see. Otherwise, it will all come down to actual image quality. We'll see soon enough.

Compared to the ATX 95, the one clear advantage of the Zeiss will be the magnification range from 23-30x, which will be very welcome to many birders contemplating their choice. As a high magnification freak, I'm likely to stick with my ATX with extender X and 70-120x range, which the Zeiss from the little we have heard does not seem to offer (yet).

Kimmo

Binastro Tuesday 8th August 2017 21:52

I am a higher magnification freak plus.
I would want a range of 20x to 200x on a top 95mm scope, if necessary with Barlows.

The excellent Mirador 70mm mirror spotter has a standard 30x to 120x zoom plus can take 1.25 inch fit eyepieces.
The Questar is an option also.

My astro scopes easily cover 20x to 200x.

Vespobuteo Thursday 10th August 2017 09:56

This would be the new Zeiss scope in the drawing I guess, the double helical focusers or possible zoom ring are seen.

I very much doubt these scopes are fieldworthy. The Questar most certainly isn't, it leaks like a sieve IME. Not the kind of scope I'd like to use in tough weather conditions.

Anyway, that kind of settles the discussion on what was going to be Zeiss' 'new product' at BirdFair. 32mm SF must still be up the road apiece....

Binastro Friday 11th August 2017 14:04

The Questar is used by several specialised military units.
I doubt it gets tougher than that.
It probably does leak.
Most astro type scopes are not waterproof.
I don't know if they use rain covers, with good quality optical windows.

Similarly early superb Russian similar scopes.

My Questars show no sign of water damage despite having had a hard professional life.
I got them cheaply because the field tech messed up the eyepieces and they could not show an in focus image. Probably after cleaning them.
It took me about fifteen minutes to take the eyepieces apart and reassemble them correctly.

Sorry, but we're embargoed from divulging details until Friday. At that time, I'll post a link to a complete video with Jerry Dobler explaining the features of the new scopes in detail. We're still waiting for pricing and specs.

DRodrigues Sunday 13th August 2017 11:27

Zeiss most probably will include all info on their site also on Friday...
It's a good new to Zeiss fans.
I find the eyepiece too short to be wide angled (compared to Kowa and Leica eps length), so the second ring can be a zooming ring in order to achieve wider AFOVs?
Nice to see that competition to the X95 will increase and look forward to see all specs, and the future replies of Kowa and Leica...;)

100% agree with all of this Hermann.

Better pic of the new Zeiss Scope taken from Twitter. Full details should be released on Friday with the opening of Bird Fair 2017.

LOL.

Henry, when you teach English to speakers of other languages you tell your students that 'should' means 'the right thing to do'.

So, I repeat, full details should be released on Friday. :t:

Ratal Wednesday 16th August 2017 17:57

That's a nice black Swaro scope she has there. Didn't know it was available in black.

Vespobuteo Wednesday 16th August 2017 18:25

The scope looks quite long, perhaps means better CA control at the edges than some others.
