Very Good information. Thanks
This girl should be my wife! Lol j/k
I cannot decide between Vortex Diamondback HD 8×42 and 10×42. Both have some good and bad sides.
Very informative video that helped me solve my dilemma of 8×42 or 10×42 , after having my binoculars for over 40 years they unfortunately developed a mold growing in the internal lenses so I dismateled them and cleaned the lenses and prisim However the diopiter thread was worn out. So I treated myself to a brand new pair of 10×42 for bird watching and general observations such as watching the ships sail up the forth.Thanks for this video, I will have many enjoyable days on my walks with my new binoculars.
Almost every other video I watched talks about the 8 x 42‘s having the better low light image due to the exit pupil.
Wow! What a wonderful explanation between the two, thank you so much! Cheers from Montana!
8X42 offer a better field of view, a large exit pupil for low light and a greater depth of field. If a person wants 10x, they should get a 10×50 which will offer an exit pupil and low light performance similar to the 8x.
Aperture is determined by the objective lens. You said 'Aperture is brighter with 10x …' = Factual incorrectness. Fact is increased x = DULLER [UNLESS something is changed, ie actual aperture, lower dispersion glass and prisms, as example],
Thank you
Before buying go to a store and try both (of the same brand and model if possible).
Until I tried both I did not believe that the magnification difference of 10x was not as big while the extra shakyness was instantly noticiable. If you can't see it with 8x, you won't see it with 10x either.
Hands down best video on this topic. The comparative examples were exactly what I needed. Thank you!
Is it worth to have both? 8×42 NL Pure AND 10×42? or not so much difference? I have already 8x, but curious to 10x But i will use 8x the most
Pretty good video. Nice job.
SUPER recenzja/porównanie dwóch lornetek. Bardzo mi pomogło w wyborze lornetki BLASER Primus 10×42. Bardzo dziękuję i serdecznie pozdrawiam!
I agree with everyone else- this video was really informative and really helped me in picking my next pair of binoculars!
Comprehensive and clear explanation video. Bravo!
Hy, what do you think about 8.5×50? Thank you!
Love the clear, concise, explanations. Extremely helpful. Thank you!
8's for me. Great everyday general use.
You say that the 10x can perform better in low light. In fact, it's the opposite!
For the ultimate in general purpose binoculars you have to go a very long way to beat a decent pair of marine 7×50 binoculars. Weather proof, great low light performance, easy to hold stable even on a moving platform, and the choice of generations of mariners. Smaller diameter objective lenses offer carrying convenience at the expense of light gathering capability. Higher magnifications give a dimmer view and a shakier image if handheld. The physics behind how binoculars work means that every tweak in one area results in a trade off elsewhere. You simply can’t get a quart out of a pint pot.
She is beautiful, exactly what you need when you’re on a safari.
Good vid and thanky. Ordered 8x
gorgeous
thank you
When you say “Hunting” do you mean killing wild animals for sport?
8x has lot more advantages than 10x.
Good video. 8×42 is a better allround choice and 10×42 a more specific task choice.
Worth to mention is that (with everything else equal) while there is a direct relation between the area of the exit pupil and image brightness(all binoculars with same exit pupil have same brightness), twilight factor cannot indiscriminately be used to describe performance in low light.
Relative brightness index describes an optical law, but twilight factor is a made up value not describing an optical law.
The main factor for low light performance is exit pupil. You need light in order to see any detail and twilight factor is dependent on sufficient brightness. This is easy to understand if you increase the magnification. For example: while a 10×42 has twilight factor of 20,5 a 20×42 will have twilight factor of 29. This does not mean it works better in low light, because the image will be 4 times dimmer. And even further:
42×42 has twilight factor of 42, which is more than twice of a 10×42. But forget to see much details in dim conditions with 1mm exit pupil! The image with 42x will be 17,6 times dimmer than with 10x. In a situation where you barely see details with 10x you will just see darkness with 42x.
Magnified darkness = darkness.
