Based on the high quality reputation, but a narrow fov on 7x35, I was looking for wider angle Zephyrs 9x35 but had to research to see what the fov on the 8x30's were. I read 444ft or 68deg afov. I got lucky.....they are very sharp with high contrast, easy on the eyes. Very impressive for older technology ! Focusing direction turns counter to most porros but that's ok...



I recently acquired a Zephyr 8X30 and, indeed, it is a terrific binocular. Not only a great view but very light (much lighter than it looks) and comfortable to hold and carry. It has quickly taken a place alongside the Leitz Binuxit and Zeiss Oberkochen as my favorite vintage 8X30. What surprises me is that if today's availability of these models is any indication, the 7X35 Zephyrs, in their time, were a far more popular binocular, a lot more seeming to have been made and sold. Not to take away from the the 7X35 - it also is a really fine binocular with the same qualities as the 8X30 - but the 8X30 has a wider FOV, is more lightweight and compact and of higher magnification making it in my opinion a preferable binocular. Perhaps 8X30 sales were hurt by competition from all the fine European 8X30's also available (although you'd expect that in the U.S., at least, the B&L would be a little less expensive) while the 7X35 had no competition except from eventually the Japanese models. Also, I've noticed looking at some circa 1950's and 60's binocular catalogs from British dealers (Frank, Davis, Moss) that although many German binoculars were sold alongside the British ones, American Bausch & Lombs are absent except for war surplus ones.

Hello Frank,

As I understand it, before WWII, the 6x30 was standard for hunters and bird watchers. The 7x35, with the same exit pupil was for the macho user, because of the size while the 8x30 was dimmer, with its 3.5 mm exit pupil and regarded as harder to hold steady. Post WWII, even the 8x30 was bright enough, because of the coatings, while tastes changed and the 8x binoculars became very popular. They were no easier to hold steady but they became acceptable. I would guess that, except for maritime use, the 7x50 was replaced with the 7x42. Large objectives mean large prisms, so the smaller the objectives, the easier it is to have a wider FOV. So coatings and a desire for wider FOV favored the more compact 8x30.

Clear skies,
Arthur

In today's post I received a Bausch & Lomb catalog published (I think) in 1952. Here are the company's descriptions of the Zephyr 8X30 and 7X35 and a usage guide:

Bausch & Lomb themselves promoted the 7X35 and the best binocular for all-around use.

I started collecting binoculars in the 50's when I was a schoolboy, and I have NEVER seen a brand-new B & L binocular for sale in the UK.

I have owned catalogues by both Charles Frank and Davis, but Moss is a new name to me; could you post the dealer's address, please?

Arthur,
Prism size does not scale with objective diameter; rather, it scales with the eyepiece field stop diameter. A 100mm bino can (and some do) have the very same prisms employed in a 6X30.

Some other myths busted:

- Bigger prisms do not improve field illumination, because what is gained by the increase in prism aperture is pretty much exactly lost due to the increase in optical path length through the bigger glass.

- Bigger prisms wil not diminish the prominence of the 'diamond'-shaped, darker blue-gray pattern seen in the exit pupil. Only a higher index prism set will do this.

But in wide angle Porro I binoculars larger prisms especially at the objective end are often needed. F. ex. the Sard Mk 43 6X42, one of the ultimate wide-angle binoculars, having enormous prisms supporting a 4 or 5 element wide-angle ocular.

Frank,
Can I take it you mean a tapered first prism? That is, the side of the prism which collects the light from the objective is wider so as to accommodate this widest part of the light cone. Not many binos employ such a prism...

It's not common but they do show up from time to time. In my collection the Zeiss Oberkochen 8X30, Kern Focalpin 10x60, Spencer Mark 30 7X50 and of all things a pre-war San Giorgio 6X30 have them and a few other I can't remember. Here's a picture of the Spencer's prisms: http://www.flickr.com/photos/binocwpg/5614511103/in/set-72157623234405689

Notarem Focus problem new [Re: FrankL]
      #5361963 - 08/10/12 03:31 PM

I knew it was a mistake buying a roof? I have just noticed that I cant achieve infinity focus on my Notarem's?
There looks like a locking ring to allow the oculars to be screwed in further, is that the correct way to rectify the fault?

I think that the Carl Zeiss Jena 8 x 50 Nobilem Super does, too.

Thank you for that, Frank. If you thought you heard a thud then that was my jaw hitting the floor, as Moss Bros are a famous UK company who're known principally as being the shop you'd go to if you wanted to hire a tuxedo for the weekend! There is a branch in my home town and I've never seen anything but suits displayed in the window. No other binocular enthusiast has ever mentioned Moss Bros to me as a place where you could buy them. It was great to see all those old names again in that catalogue; a real pot-pourri of mid-60's binocular life.

On the Shopgoodwill site today there are 81 items in the Binocular section which include a Zephyr 8x30 and a Zephyr 7x35. It also includes; B&L 7x50, WW2 6x30, Leitz 7x35 Trinovid, WW2 RLN 10x50.
Imagine people just give these away, many maybe thinking that they aren't worth anything!

They usually give them away for a good reason.
Not always in the best overall condition & not always in good working order.

Some get lucky, others do not.
I was one of the unlucky ones.

Hello Planetmaic,

I imagine that if one is renting an outfit for Ascot, a binocular would be a suitable accessory.

Maybe I have been lucky, but all the premium glass I have picked up at places like the Sally Ann or Value Village have been in good shape. There may have been the odd 'dog' over the years, but those are the ones I don't buy. I think there was a Nikon once with a loose prism.
I think most people are smart enough and/or nice enough not to to give broken stuff to a charity shop.

Several years ago, I noticed that the Oxford (UK) branch of the Oxfam charity shop chain was having what they called 'a binocular week'. I walked in binocularless, and walked out a few minutes later with a bag-full of collectible pittance-price bargains (some pre-WW1), plus an almost-new pair of Swarovski Habicht 10 x 40W Porro's that had a 23 price sticker on them. ALWAYS check out charity shops 'cos they sometimes haven't got a clue!

Binoculars on UK TV [Re: Jae]
      #5384379 - 08/24/12 11:24 AM

As many of you guys like disassembling, repairing and rebuilding binoculars, I thought you might be interested in this:-

For UK viewers, they're screening a TV program on the manufacture of binoculars, on Monday 27th August. It's on the Quest channel (Freeview 38) at 23.00hrs, and will probably last around 15mins.
