Unfortunately that's not true: the image size scaling in porros is insignificantly affected by the FOV, if at all.

There is a Russian/USSR 8x30 pair with an AFoV=104*!
Those are the binos with the largest AFoV I have come across, but there are quite a few binos made in the 50s and 60s with AFoV>80* or even 90*....

A colleague has discovered 7 new species of birds, one of which bears his name (seriously). I guess when his Swaro monoc couldn't ID the bird, he knew that was a new species.

The "orange spot" issue is caused by reflections of side light by the ocular lenses and a simple fix is using your hand to shield the eyepieces, as you said yourself. I have four Victory FL binos...

Mark,

To me staring is what you do when you gaze off into the distance without focusing on anything, regardless of your eye dynamic accommodation.

That's an excellent choice. Personally I prefer the SV 10x50 for a number of reasons, but the SLC 10x56 is brighter (due to its larger EP and AK prisms) and that's important to you.

Hi Bill,

Another (perhaps less ambiguous) way of saying this: try to focus with your eyes at rest.
That's easier said than done for young people who have an excellent eye accommodation. However the...

For objects at such a close range there is no question that porros are far from ideal. But for more distant objects have you found any porros that satisfy the remaining criteria?

Henry,

Why is 8 necessary? (all other criteria are pretty obvious).
It eliminates all porros I.

So true, Chosun. I love my Victory FL 10x56, and if multiple choices were allowed I would have also ticked the 10x56 box (not only the 10x42 checkbox, for my Victory SF 10x42).
