I just received a new binocular the other day so I set off to do some comparisons to my other binoculars.
I spent about 2 hours in the backyard last evening and compared three binoculars against each other for brightness and clarity until it was dark.
My new binocular received is a Steiner Nighthunter XP in 10x56.
For a fair comparison I tested it against my Leupold 8x42 Golden ring HD and Meopta Meostar B1 10x42. I did not include my Swarovski EL swarovision 8.5x42 as I know how it compares to the Leupold and Meopta.
All were about on even terms as far as sharpness (leupold best) and CA (again leupold best).
The big shock to me was the brightness in low light. The 56mm nighthunter did not show any advantage over the other two binoculars! None at all!
Another surprise to me was the 8x42 Golden ring HD had no brightness advantage in low light over the Meopta 10x42.
I was able to pick up more detail at distant objects with both the 10x glasses over the 8x42 in very low light levels.
This leads me to believe that perhaps the pupils in my eyes have no use for the larger exit pupils of the 8x42 and 10x56.
For the record I have 20/20 vision.
Any ideas?
