You just proved that the beam of light projected through those binoculars is not the same diameter as the objective lens, which disporoves the statement that was made in the post that I quoted. In other words, a 50mm objective lens does not result in a 50mm beam of light reaching your eyes. Thank you for demonstrating that fact. As for the exit pupil that was mentioned, that is only a calculation, and it alone does not determine the amount of light that can be transmitted through an optical device. A pair of binoculars with very high quality lens coatings on 42mm objective lenses may actually transmit more light than a pair of binoculars with 50mm objective lenses and much lower quality lens coatings. And your demonstration proves nothing about the objective lense size being a factor in how easy it is to line up your eyes with the eyepiece to see a perfect image.

You shoulda gotten better coatings for your tape roll i guess

It comes down to reading comprehension skills.

Clearly someone is not grasping the meaning of the word "RELATES" .




But, I will agree with elkhunter11 this one time.

Then the next time my wife sarcastically says
that I'm ALWAYS right, I can remind her of this post.
