As to the EII, is there a reason you prefer the 10x to the 8x? I've considered the 10x also but don't like the close focus distance and a pretty limited Fov.
Here's something from a good comparison article I found
The good things - what the Nikon does better than the Habicht:
1. Field of view is much wider, 154m vs. 136m. Really a wonderful thing.
2. Flare is much better controlled in the Nikon. A big plus, but with severe trade-offs...
The bad things - what the Habicht does better
1. No way around it - the Nikon images are much darker and much redder than the Habicht´s, and this was my crucial point, I just missed that Habicht sparkle, despite extreme sharpness the Nikon is almost a bit depressing in comparison. Like in the EDG I suspect Nikon is making the images darker than necessary by strong internal baffling, blocking out more light rays not parallel to the axis, crashing the blacks and thereby increasing perceived contrast at the expense of brightness.
2. Contrast and sharpness: The Nikon is - typical for Nikon - brutally sharp, but if we look at finer details and textures, it cannot quite match the Habicht.
3. Build quality. 30 years of warranty for the Habicht. Bulletproof. The Nikon feels nice in the hands, build quality seems very good, but I would not want to drop it. I admit this is pure gut feeling.
The Habicht is about 50% more expensive, which I believe is totally justified - in fact, for a Swarovski product and premium quality it is a steal.
I returned the Nikon with a sigh, simply because I have this Austrian bird of paradise. But if price, flare control and field of view is more important for you than one of the most lovely glowing images in binoculars... the E2 will not disappoint you, and you should buy one while you can.
