    Default 15x70 Binoculars field Of View Question



    My Oberwerk 15x70 LW binoculars are actually 15x64 binoculars. This is due to an internal stop/aperture, which has been confirmed by the people at Oberwerk. They advertise the 15x70 LW binoculars as having a 4.3 degree field of view. What is the actual field of view at 15x64?

    The binoculars are still good with the 64mm aperture. I could find M104/Sombrero galaxy, which is close to 30 million light years away. A great finder with the red dot scope. Thanks to you all.

    Already really had the answer to this question. I do wish vendors would be honest with the specs. If I knew the 15x70 were actually 15x64, I would have gotten the 12x60. Same aperture with wider exit pupil/field of view, and a pound lighter.

    As per
    https://www.cloudynights.com/article...r-review-r2854

    The 12x60 Oberwerk LW are 11.4x51 when measured !

    If you can see the Sombrero Galaxy in your binos, I would consider them quite good.
