11×56 vs. 8×56 LW FOV

Your catalog lists the specifications for both these binos with the same (FOV of 6.0)
How is that possible? I own the 11×56 LW but was thinking I’d like a wider FOV.
What is the FOV on the 8×56 and 11×56? If you could convert that to feet of view also it would be helpful for me but it’s OK if not.

It’s actually true that both models have the same 6° FOV. The 11x model has a wide-angle eyepiece design, the 8x model does not. Similar to some other models such as the 9×60 and 12×60– the 12x actually has a wider FOV (5.7°) than the 9x (5.5°)! Our 11×70 is 4.5° and the 15×70 is just slightly less at 4.3°. In all these cases, wide-angle eyepieces are used on the higher magnification model. This also affects AFOV (apparent field of view), which is typically 50° on the lower magnification model and 65+° on the higher magnification model.
But back to the 8×56 (and 11×56)- the FOV is 105m at 1000m, or 105 yards (315 ft.) at 1000 yards. Your 11×56 is about as wide as it gets at this relatively-high magnification. But if you’re looking for something wider, take a look at our 8×42 Sport ED. It has a huge 8.1° FOV, is small and lightweight, and is also apochromatic due to the ED objectives. It’s actually our finest bird-watching binocular, but I really like it for astronomy as well. It would nicely complement, rather than replace, your 11×56.
