I doubt we use them differently. Sometimes one sees a target like a bird first, then brings up the binocular; I could even suggest that the store nail a Norwegian parrot to the tree in their parking lot for the purpose. But often one is only scanning for something or exploring a landscape, and must focus on whatever's there.I might be jumping to conclusions but I think I see the difference in how we are both using these binos. You said "Perhaps it would have helped to have a yellow bird in the tree". I am using these binos to look at subjects that grab my attention, as I hope you can tell from reading my review. Your description of looking at a tree with no bird in it suggests you are just looking at an available scene and then trying to analyse how the bino has represented it. I humbly suggest it would be better to wait until any kind of bird lands in that tree (or anywhere else) and then focus on the bird. I think having a genuine central subject of interest would enable a better assessment of the bino's view.
That's insulting and irrelevant. I clearly said that I had no such issue with other bins, and am simply curious why I seemed to here, and whether anyone else has.If you have a continuing difficulty in seeing what is in focus and what is not, it suggests to me that you need to re-set the bino's dioptre adjustment and/or visit an optician to have your vision tested.
