But how can you test so many similar binoculars at the same time. Mostly the seller don’t have that many in stock evenMy advice, as always, is to try at least three similar binoculars and take the best, even if this is a demonstration binocular.
Buy the one tested, not a boxed similar binocular.
If possible, try six or twelve.
Will do. I assume I am to refocus the image with the dioptre ring set to its furthest extent of travel. Two secsI should have suggested one more thing. Could you rotate the diopter adjustment ring as far as it will go in either direction and photograph the roof through that side again?
Thanks,
