Testing binoculars
There is a trick to testing binoculars that most people dont know about,
Instead of taking them out of the shop and looking down the street and say "Wow are these sharp"!!!
What you should do is find a straight line ie a shop awning or the edge of a large display window.... then REVERSE the binoculars and look though one side at a time at the straight edge and rotate the edge through the 360 degrees of the lens.
If the straight line "KINKS" near the outer edge then the lens/s/prism are not true. do this to both sides of the binoculars.
Also you can also see any mildue/bits of plastic etc inside the binoculars.
you would be surprised at the amount of rubbish is inside of some of even brand binoculars.
