Thread: binocular question

The first number is the magnification power.
The second number is the objective lense size in millimeters and determines how much light it will gather and transmit to the eye.
To determine the light gathering ability you devide the first number into the second number. The ideal ratio is 5.
Such as: 7x35, 8x40, 10x50 and so on.

Great answer and no name calling. Way to go guys.

Great answer Gary. I learned something new today!!!!!

8x32 or10x50 will gather less light all else equal than 8x40 or10x50s. Noticable in diminishing light situations. Having said this other factors can affect their abilities to function in low light. $$$$$ can be an indicator

10x50 will gather less light than 10x50s??? Is that because of the s.

10x 40s sorry. Never got the hang of proofreading. Notice that about 95% of my posts are edited.

So who has a good set of binoculars they would recommend. I have been looking at the Nikon Monarch 5's but havent pulled the trigger yet. Thinking I may ask Santa for a good pair. I also like the Vortex. Never thought binoculars were so expensive til I started looking but they are almost as high as a scope.

X's 2 on the Vortex.
