Tell us more about the GA lens coating you mention?
I am not familiar with it.

Sorry mate, I was referring to the thick GA coating itself....the protective rubber coating of the binocular. It's thick and chunky. Doesn't it stand for Gummi Armor or gummy bear or something in German?
As for the lense coatings, well, I have no idea what they are but they're bloody good. The light transmission is right up there at the top of any bino ever made. Perhaps, from memory, only the fujinon 7x50 equals or slightly betters it. So, apart from being a porro, they're obviously doing something right with the lens coatings. Without going into detail, The 10x has very few optical weaknesses from what I can see. The occasional glare of the 8x is completely absent. I will say it's a ruthlessly revealing glass. The contrast and on axis clarity are monstrous. In quick direct comparison, The excellent Nikon Ell looks washed out...lacking in contrast and clarity.
Last week i was viewing a funnel webbed spider's lair in the hole of a tree trunk. I was about thirty yards away(close enough). Half way between myself and the tree was a post with a single spiders web thread swaying in the breeze. I had four binoculars with me -
The 8x30 Habicht
The 8x30 Habicht Swedish military with reticle
The 8x30 Nikon Ell
The 7x42 zeiss bgatp
The zeiss had the easiest and most relaxing view of the spiders lair.
The Nikon was also easy. Slightly dull but sharp and good. And Easy quick eye placement.
Both Habichts however required eyes to be properly placed, then kept locked in place. Easy once practiced. Then the differences became clear. Firstly, while focused on the funnel webb nest tree, I suddenly spotted the single thread of spiders web blowing horizontally (15 yards away, half way to the tree), invisible in the other bins. They just couldn't pick it up, even when focusing directly on it. It was just too fine for them. Not enough contrast.
Using both the little Habichts (optically identical) it stood out..really stood out. I realised this was optical superiority plain and simple.
Then I focused on the beautiful thin peeling bark of this big gum tree with all binos...arms rested on car window sill. It looked so sharp and pleasant in the zeiss and Nikon. I was totally satisfied. but then I got out the Habichts, and I could further resolve which way the tiny pieces of shedding bark were actually twisting due to the tiny shadows cast by them. Unbelievable.
This acuity stuff can get a bit silly...fortunately I've still got good eyes, but maybe in ten years I won't be able to resolve all of these differences, and hopefully I won't care obout or know what I'm missing :-O
Having said all that, if I had to sit there all day waiting for that spider to appear, I'd choose the zeiss because of its lovely relaxed and forgiving view. It lets your eyeballs and head loll about just a bit and still see everything looking lovely and lush....and in isolation, not wanting for any more detail whatsoever.
Just some recent observations,
