I 100% agree with you, Hermann, although personally, I thoroughly enjoy those 'problems' you refer to, and might prefer to call them 'challenges' instead. 🙂One of the problems many people here have is that they use too many different binoculars. Most binoculars are sufficiently "different" that you have to get used to them. That may take a few days in the field, it's not something you can do in a shop. And if you only use one or, at most - two different binoculars, you'll get so familiar with them that all those "difficulties" mysteriously disappear. Provided you found the correct IPD and so on in the first place.
