Right on JG. Its as if saying that these bins are terrific is somehow disrespecting other brands and / or models so praise of them cannot be tolerated.

Hello! Just ignore bajjanamnam.
The Passion HD is really a interesting bino, but are they made by kamakura?
Im not sure about that. Looks to much like binoculars made by light optics works,
Why is IT so secret? Maven and tract have no secrets about that kamakura make binos for them.
Im just curious.

It is very nice indeed to receive 3 posts from Sweden in so short a time
Is there a fire in the roof?

Passion HDs are made in Japan but I don't know by whom.

Hi BB

I used to work for a Swedish company called Forsheda based in the small village of Forsheda just to the west of Varnamo in Smaland and from time to time I heard people say 'there is no fire in the roof' meaning that there was no emergency, no need to hurry, nothing is urgent. Perhaps this saying is only spoken in Smaland.

Perhaps Bajjanamnan was used to using the 11th. century or earlier aspheric lenses from nearby Visby. These gave a wide field.

I have some sympathy.
Minolta Standard MK 10x 50 7.8 deg,
8x40 ( Probably 8.1x) 9.4 deg.
7x35 11.05 deg.

Swift, Hoya, Greenkat 10x50s 7.5 to 7.9 deg measured.

8.5x44 HR/5 8.26deg measured etc.

I make the 10x42 HD Conquest 6.65 deg.

Not quite, the Swedish saying is (if you translate it word by word) "there's no danger on the roof"
Another similar one is "There's no cow on the ice (as long as the ass is on land)."

FOV for the 8x42 GPO 125m/1000m, I guess is OK for the price range.
Only sold in the US?

You can buy it in Europe from GPO, but under the brand geco.

They (Geco Gold AKA GPO) seem to be in the same price range as Zeiss Conquest HD or slightly above.

GPO eyecups

As I mentioned in post #1 the eyecups have only one intermediate stop, but they stay put at any position from fully collapsed to fully extended; they are of very good quality.////Peter.

Do you happen to know the thread diameter needed? As my Canon 10x42 takes 52mm glare shields, that might be the size here as well.
It appears that the thread diameter is 38mm---Mike of GPO will try to confirm that with his German partners.

Thanks, Peter, that makes the hood selection easy.
If it is 38mm on the 8x32 version, presumably the 8x42 will be somewhere around 50-52mm.
Hoods are a surprisingly helpful addition to a binocular, they really improve the view.

Vespobuteo, I thought the 3-letter word meant the other animal, and possibly other readers might make that mistake: apologies if I insult them. "Jag anar ugglor i mossen," I said to myself, "Hr ligger en hund begraven!" Then I turned to Google and was corrected. This is the webpage that helped me out (it also has the other 2 sayings).

To clear this up, I need to confirm that I gave Peter incorrect conversion data. Sorry Peter. I just put a caliper on this myself and the inside diameter of the objective hold ring on the PASSION HD bino measures 1.654", equaling 42.01mm.

Thanks, Etudiant, for posting. Like you I believed that the figure of 38mm that I received from GPO was for the 32mm HD, but there is no such a model so it must have been an erroneous measurement for the 42mm. So I have looked at the objectives again and used a ruler to approximately measure the diameter---got about 42mm so this is not a threaded fitting for a hood or filter but the usual threads that most binoculars have. As far as I know only Kowa, Canon and Leupold have threaded fittings of the type you desire, but not the GPO.

Thanks, Mike, for your clarification. So there you have it: it's the usual objective hold ring, not threaded fittings for hoods and filters.

Thanks for clearing that up VB. The next time I see a cow on the ice in Sweden I will make sure I keep my ass on the land

Filter thread sizes and inside measurements are not the same.
Also somewhere I saw that T2 and 42mm camera lens fittings are the same. They aren't. They have different pitches.
Even the form of threads differ.

I made the bad mistake of putting a new 50mm f/1.1 Zunow lens, Nikon bayonet fit on A Kiev. I marked the lens. They are not the same. Neither is the old Contax bayonet.

I have used 2 inch astro eyepiece fit filters on Canon IS binoculars with two step up or down rings on each barrel to get the correct threads.

Hi Peter, hi Mike,
Thank you for tracking this down completely, no threads on the GPO objective ends. Too bad.
It seems an inexpensive nicety, which allows filters or lens hoods to be fitted easily. Adding hoods, a suggestion initially made iirc on this forum by Rathaus, has improved the view from my Canon 10x42s. The GPO view probably does not benefit as much.

I'm not sure about why anyone wants to put a filter on your
binocular. Looking at the sun ?

I tried a protective filter on a spotter once, harmed the optics
big time.

Find an optics designer or company rep who recommends it.
You won't.

Binoculars are not designed for filters, unless a specialty for
military, etc.

No argument on filters, I switched to a hood to protect the objective lens on my spotter because the space between the filter and the lens fogged routinely. That said, protective neutral filters or polarizing filters can make sense on seawatch, or when pushing through brush, so there is use for them.
Hoods do cut glare and improve contrast, at the cost of increased bulk. Worth it for me, ymmv.

Pardon my ignorance, but what does a hood (whatever that is) on a spotter have anything to do with a hood for a binocular (whatever that is, too)? No offense, but I find filters useless on any optic.

A hood will help shield, side or direct lighting that adds glare, flare
to the front of your optic.

Just try putting your hand over the front side of your objective when
viewing in difficult conditions. It helps a lot.

The newer Nikon Fieldscopes have a retractable hood, that is very
nice for the purpose.

The only drawback is the added length.

That does not work for me, at least not in a satisfactory manner: doing so helps you get rid of glare in the lower part of the FoV, which becomes almost glare free, but you see....your hand in the upper part---so you gain some and lose some.

Found this pic of a Canon 10x42 IS with hoods attached, it does not look bad at all.
