throughout the many years, quite a few binoculars have passed my hands, and now I have scaled down the collection, as shown in my signature.
The Swarovski 8.5x42 EL Swarovision have a constant performance across the whole field:
sharp, CA next to nothing, other aberrations next to nothing, distorsion next to nothing.
The most comfortable for my hands are the Leica Ultravid 7x42, and they also allow to push the slim Astronomik nebular filters into the eye guards - a nice feature when you want to see the California Nebula or other big faint fuzzies.
The highest contrast and the highest light throughput offer the unfortunately discontinued Docter Nobilem 8x56 with the oversized Porro prisms, see also http://www.astronomy...uly-2019-a.html
I am tempted to rate these Docter Nobilems among the other (8 x some aperture) binoculars, like the Docter ultrawide eyepiece among the other ultrawide eyepieces.
Not sure, if I would dare to call one of these the very best binoculars, but they are all very good,
for each observing need its own.
