Hi Frank,
Wow. thanks for posting the photo link for your new acquisitions. I especially liked seeing/reading about the Ross 10x50, and the Zeiss U-boat 7x50 binoculars.
Lucky guy to have such distinctive binos.
Phil

SARD 6x42
Another common problem with these is the plastic focusing grip. They tend to crack.
Also, there are better ways to design adjustment lock for the diopter setting.

45 deg LOS inclined Flak 10 x 80, the Busch design:
Most are uncoated . My dkl 81925 Schneider( Kreuznach) has cryolite coatings, which are more efficient than MgF2, but are , NB ,soluble in warm water. I have several partially coated Leitz. Sometimes one sees somewhat oddball coatings on cxn (Busch) production . IIRC, those were early
multilayers.
I have about 100 pages of the Busch 10 x 80 design Flak binocular plans, from a Leitz archive microfilmed just after the war ended.

You're right about the SARD 6X42 focusing rings - they're plastic and not a very durable looking plastic either.

You mention "oddball coatings" on cxn 10X80's. Are you referring to the late-war red/orange coatings seen on some German binoculars? I have these on my U-Boat 7X50 and am trying to learn how they differ (other than color) from the the usual dark blue coatings. Are they an early type of multi-coating? The ones on my blc U-Boat perform very well - bright image and almost color neutral (ever so slightly warm). Also, the exterior as well as the interior of the lenses are coated unlike my beh Porro II's where only the interiors are coated (could have been coatings on the exterior but I doubt it because no traces of it can be found even at the very edge of the objectives).

Zephyr new [Re: FrankL]
      #5103585 - 03/03/12 09:58 PM

Hello Frank,

Is the Zephyr coated? There are a surprising number of the earlier uncoated models floating around.

For a 7x35, the Zephyr may be a little narrow, but my main complaint is minimum focussing distance is about 7 meters. For bird watching, it is could be a little closer.

Nice collection, in any case,
Arthur

Zeiss Dialyt new [Re: FrankL]
      #5103598 - 03/03/12 10:03 PM

Hello Frank,

I consider the 7x42 Dialyt to be close to the best compromise of any terrestrial binocular design. Good FOV, good ergonomics, brilliant, contrasty image, 6 mm exit pupil, neither too big nor too heavy and because of the Abbe König prisms, there is even a slight stereo effect.

Happy collecting,
Arthur

Hello Arthur,

Yes,the Zephyr is coated and it is a nice fairly color-neutral coating too. Close focus isn't great but the Rochester Zephyr's is about 1 meter closer focus than the Japanese version's.

There's something about the Dialyt 7X42's ergonomics - it's just so comfortable to carry and hold. I love this binocular. It's reputation is well-deserved.

I have seen the red/orange coatings which you mention on the blc KM 7 x 50. I have seen specimens, but do not have one. From the specimens which I have seen, the red/orange antireflection lens coatings were not used on the 8 x 60 handhelds, nor on the 8 x 60 deckmounts.

I have seen such red/orange coatings on several Busch (cxn) production Flak binoculars of the Busch design.

Some of the Busch design 10 x 80 from Busch, cxn, were made under great production pressure, it seems: Some of the objective lens elements were centered during cementing by simply placing them into their cells before the balsam cement had cooled. The evidence is balsam cement overflow on the cell wall.

I believe that I might be able to find material to answer your question, but it has been decades since I looked at some of the records, and finding a meaningful answer might take days.

My 45 deg. inclined 25 x 105 from Schneider Goettingen (Albert Tronnier (RIP), Chief Designer, who worked at Farrand and for Frankford Arsenal (defunct) in Philadelphia in the '50s and '60s. I corresponded with him briefly) is not coated. Most of those are not coated. The objectives are of telephoto construction, as in the similar Russian TAL (Novosibirsk) 90 deg field, yellow tint image 15 x 110, with 45 deg. inclination of the line of sight. I saw a specimen of a coated Schneider Goettingen 25 x 105 about six years ago. It is not far away. There was a 15 x 105 from them also. I have seen only one of those. IIRC, it was coated.

WW II German antireflection coatings have probably been discussed in the Peter Abrahams forum. Google gets into that forum.

How do Abbe-Koenig prisms enhance stereo? Is not the axis of each objective lens separated from the axis of the other objective lens by the IPD distance? Am I missing something about Abbe-Koenig?

A-K prisms new [Re: Gordon Rayner]
      #5104144 - 03/04/12 08:37 AM

Hello Gordon,

On the Dialyt, the oculars are somewhat more closely spaced than the objective lenses. For a roof prism glass, this is unusual. So in comparison to Schmidt-Pechan, but not to Porro binoculars, there is a slight stereo effect.

Clear skies,
Arthur

Hi Frank,
I have long lost your contact info.This is Mike Downs in Florida. I know I sold you some Canadian binos and I think I may have sent you a few old french glasses 3 or 4 years ago. I also commented on the HMR designation while you were searching for a definition. I hav'nt viewed your collection since then and must say the quanity,quality and rareness of your group is amazing.I doubt duescthoptik has anything on you now.Outstanding!!!!

Hello Frank,

I have always found the Huet binoculars to be well made, but I have never owned a civilian model. The Paris Modèle 1951 is marked waterproof, if my French is holding up.

Happy collecting,
Arthur Pinewood

Hello Arthur,
Yes, means waterproofed. The binocular is well-sealed with rubber gaskets so although by today's standards it may not be immersion proof it does look reasonably splash proof. I've seen a circa 1960's French military binocular manual and this manual references the binocular as "Modèle 1951, Étanche". The manual also includes the WWII U.S. Army M13 6X30 and M15 and 17 7X50's which apparently the French also used post-war. The manual describes these binoculars as Étanches but not as waterproof as the Modèle 1951 which if they were not gasket sealed is probably true.

Good to see the list, and how do you like the Zeiss

Hello Jerry,

Get many on eBay but have to look carefully to get good prices. Regardless of what mostly unknowledgeable but honest sellers may state most are in need of some kind of repair which I enjoy doing. Lately getting more from other collectors. The Ross 10X70 came from a lady in Toronto who just bought a house and found it in the closet. She contacted the sellers but they didn't want it so it fortunately wound up with me.

Compared to other 50's-60's binoculars the 10X50 Oberkochen is incredibly well-made (except for outgassing which may not have become evident until years after manufacture) to the point of overkill. It's also exceptionally compact and well-handling for a 10X50. Very wide angle view and good definition but compared to other binoculars of simpler optical design, the view is a little dim because it has just too many lenses/light reflecting surfaces. If this binocular were made today with modern coatings with 90%+ light transmission it would be a killer.

Frank
