Hi,
I just received the Bushnell 7x26 from amazon.com yesterday. It is my first binocular. While checking it out I noticed that a few things:
1. The manual says I should adjust the Interpupillary distance (IPD) so that the views from both eyes merge into a circle.
My problem is, if I adjust the view to become a circle, I get dark edges on left/right sides of the view field. I need to slightly enlarge the IPD so that the merged view circle becomes a ellipse-like shape to avoid the dark edges. I tried with or without wearing eye-glass (adjust eyecup down/up accordingly) and the experience was the same.
2. My second observation is that the sweet point of view from the above adjustment is too narrow: if I move my eyes slightly, which happens a lot since I'm hand holding, I start to get dark edges around the edge of the view. The center of the view is always bright & sharp.
I just want to check if this is normal or my exception was too high. I have a feeling maybe that's 'you get what you paid for'. Will the Leica 8x20 BCA be better in this regard, since it costs 2x the money?
Thanks,
John
