I compared my green 8x30W IF with my friend Nikon 8x30 eII on top of a building looking at the city and park at noontime with full sun. I noticed something.
1. In the green Habicht 8x30W IF.. everything beyond 15 meters are in focus to the farthest.
2. In the Nikon 8x30 eII... even things beyond 50 meters are not in focus with respect to the farthest.
In other words. The green Habicht 8x30W IF has greater depth of field. Is it because the Nikon 8x30 eII has greater magnification more than 8X? perhaps it is 8.3X? This may explain the green Military Habicht much greater depth of field. Is the standard black Habicht also like this.. with very great depth of field? With it this good. there is no problem with individual focuser because everything beyond 15 meters are in focus so you don't need to adjust the focuser.
Well. How about view between the Habicht and Nikon 8x30 2II in pure daylight with full sun. The contrast of the Habicht is just so incredible and stunning.. I didn't think I'd say this myself after reading other describe it.. it is so refractor like making the Nikon almost like a Catadiophic with lesser contrast. My friend after seeing my Habicht decide to sell his Nikon. This is how good the Habicht is!
I see you noticed that objects seen on the edges of a Nikon 8x30 EII are not in focus when they are not at infinity. This is because large field curvature which is known as "pincushioning" has been designed into this binocular. On these close objects you can dial the the edges into sharpness but they will lose sharpness when viewed in the center of the field. When looking at objects at infinity everything will be in focus over the full field of view.
You can see this large "pincushion" field curvature when you place a nearby straight object like a telephone pole at the edge of the field of view. You can focus it into sharpness. Move the binocular so the pole is in the center of the view and it will be out of focus but it will be straight. This is how the EII was designed.
