Started some 10+ years ago when I worked on oil plattforms in the North Sea.
First came across a Fujinon 7x50 FMTR-SX which was so easy to look through and 3D. Looking at birds on the helideck made me want to buy my first binocular for watching stars.
After resarch, Fujinon 10x50 FMT-SX was bought… Large AFOV, crystal clear and 3D effect was noticable.
Then I bought a Nikon 18x70 Astroluxe. HUGE AFOV and so so so nice looking at stars.
Moved to another oil plattform, where they had a Black Zeiss 7x50 marine binocular and a Zeiss 20x60 IS binocular. Both clearly Worse then my pair, small AFOVs.
So for ME its ease to look through, AFOV and 3D porro binoculars.
