I have also done a side by side comparison with the 15x70 Bears and Oberwerks 15x70. The Oberwerks are easily the superior product. Much brighter and wider field of view.
Ron, I now own both the Bears and the Oberwerks, and the fields are exactly identical...They share the exact same optical elements! See my prior post...the only substantial difference is one optical surface with a milti-coating on the Oberwerks, the front surface of the objectives. All internal element faces reflect the same blue tint as the Bears, indicating a MgF2 coating. I don't see how you could have noticed a difference in width of field, unless the Oberwerk you were comparing is a different model than mine (15x70mm). Physically impossible given that they are the same binocular. I even used different binoculars over each eye, to superimpose the fields on one another. They are identical. The better front-surface coating on the Obies can at most contribute a few percent to total throughput, and it's almost impossible for me, anyway, to notice a brightness difference that slight visually. I'm taking them under the stars tonight to see if I can notice a difference for myself. Are you really sure about your observations? Could the Bears have had dirty optics? Could someone have passed you a Fujinon in the dark, and told you it was an Oberwerk? I'll have both of these side-by-side at Binopalooza, if anyone wants to see for themselves.
