Zeiss Diascope successor

The first diascopes were first seen in 2007 I think.
10 years seem to be a normal model lifecycle for optics.
Will there be a new Zeiss scope at BirdFair
and what improvements would you like to
see compared to the current model?

A successor is on the way and an 85mm version has been tested by some professional birders in the UK. Not clear if it was prototype or a more advanced model. 'Very light' I'm told. My source thought it might be released next year.

Zeiss is very secretive about these new launches, which is a shame if you're thinking about changing your scope. I would have postponed my Swaro SV purchase if I'd known the SF was imminent.

This is all I know, does anyone know any more?

Well, that was quite a lot of news.

Perhaps thinner glass, shorter body, integrated eye piece,
slimmer magnesium chassi might shave off some grams.
No huge weight differences between the current scopes,
and I'm not sure if weight would be a major selling point on a these big scopes?

To me the weight would have to go down to around 1650-1700 grams like the ATS80 or Kowa 773
to make me interested in a large scope. And perhaps be as compact/short like the 773.

Would really prefer having one single scope instead of a something like the 65mm + 95 mm ATX, that would mostly be awkward to me.
That said the 95mm ATX is getting quite popular around here.

Kowa 883 - 1895 grams with 25-60x
Diascope 85mm - 1997 gram with 20-75x
Swaro ATX 85mm - 1965 grams with 20-60x
Leica APO-Televid - 1955 grams with 25-50x
ATS80 - 1640 grams with 25-50x
Kowa 773 - 1705 grams with 25-60x

What and/or who is a professional birder ?
OK, don't name names but I'd be interested in your definition mainly because I'm not aware of such a creature

Zeiss have recently started to name names in their marketing, Simon King etc.:

Perhaps it's the Biologist Michael Tiefenbach:

Thank you, I think I understand that distinction.
That 75mm diascope looks a little different to mine.

Really simple, Mike. Anyone who makes a living from the hobby. For example, perhaps someone who works for the BTO, works for a bird information service, a bird tour company, carries out environmental surveys, etc etc. HTH

Thanks dogfish, I get the tour guide example and that's the only example I could envisage.
But equally I know a lad who once worked at BirdNet taking messages and distributing information -he wasn't a birder.

I would like to see a 100mm version!...
I hope the X95 success will stimulate Zeiss to do such a version... I know that other alpha is preparing a reply to Swaro but can't tell which...

There are one or two regular contributors to this forum who have links to Zeiss, but I fear they've been forced to sign the Official Secrets Act

Hi Vespobuteo

As you mentioned above, Simon King. He is a zeiss ambassador and uses its optics. He will be at Birdfair this year as always, why not pop by and have a chat with him?

Anyone seen Birdwatch magazine this month? No?

Probably worth a look if you want to find out more about the new Zeiss scope :-)

Ah. Now that would be telling wouldn't it?

There's a review in there of the Zeiss Conquest Gavia 85, done by Mike Alibone their resident optics guru. His key takeaway is that it is lightweight for an 85mm scope, performed well in low light conditions and "image stays sharp across the whole magnification range". The eyepiece is 30-70x.

SRP is expected to be around 1600/€2100/$1900 and it will be on show at Birdfair apparently.

There's also a Zeiss ad for the new scope in the mag.

This link has a photo:

Yes, seen the BW piece. I was hoping the new scope would be a top-of-the-range model but I suppose there could still be one on the way.

Ok, thanks,
I guess the possibility for a new Diascope this year decreased
with this Conquest-scope.

I found more details here:

http://www.foto-wannack.de/spektive/...previous-photo

Specs even include the focal length (494mm), perhaps because there is a 1.25" astro eyepiece adapter.

30-60x zoom is wide enough (56.6 AFOV @ 30x, 79@ 60x) and close focus is unusually short at 3.3m.

thanks for the link Henry,
nice photos,
very light, 1700g, even lighter than the swaro ATS80,
just wonder why not start the zoom range at 25x...
FOV will suffer a bit from it,
brightness will probably be fine anyway, but still a bit annoying..
nice with the astro-adapter though,
