@koshkin Related: The Dark Lord himself recently talked on his YT channel about how pure optical performance of a system is one thing, and how you eyes interact with that system is another thing.
For example, you see better out of a spotter than a riflescope because your eye is much closer to the spotter’s eyepiece. Why?
He says that when your eye is close to the eyepiece, there is less room for visual clutter to distract your brain (i.e. the hot chick next to you bending over to collect brass-
my example, not his lol). So, said brain can put more resources towards the actual image you are interested in and therefore, it appears sharper to you.
Of course, compared to a smoking babes butt, I am only
nominally interested in the riflescope image. So, in theory, said ass will appear to me in
razor-sharp UHD 100k cinema-scope while my riflescope image will appear to my juiced-up brain as but a 8-bit Atari toadstool of a target.
So, your
brain is the reason binos look sharper, both by combining/interpretating two images vs one PLUS the close-to-eyepiece phenomenon above.
Other tidbits from his excellent show: March (and other scope manufacturers, it’s hard to tell unless you have insider knowledge) tend/tended to build scopes that are optimized for the scope’s max magnification. In March’s case, this was because their scopes were often used for benchrest or f-class sort of events where people mainly used the max mag.
There is a downside of this ”optimize for the max” strategy. The combo of how your brain works + the scope’s exit pupil + your eye’s “entrance pupil” in differing light = it’s actually usually better to optimize the optic at a lower mag because said optimization is more
effective (noticeable to the eye) there.
There may be more to it, but because I don’t have time to re-listen right now to
really understand and let it sink into the mush that is my brain, I’ll let you watch the vid yourself.
