What is the difference between 10x50, 8x42, 10x42 &amp; 10-22x50?

The first number is the power of the lens, that is how much it will magnify the image. The second number represents the diameter of the lens in mm. They work together to calculate a number called the "exit pupil" or "exit ratio". Take the lens size and divide it by the power to get this number. The higher the number, the brighter the image. For example, 10x50 will give an exit ratio of 5.0, 8x42 would be 5.25, 10x42 would be 4.2. In my opinion, the exit ratio is more important than the power. My favorite binoculars are 8x50 (6.25) but I also just bought 10x50 as a gift who is delighted with that configuration. Stay away from high-power binoculars. They, for me, are too hard to keep steady due to the high magnification. I hope this helps. -Norm

I didn't see an option for 8x8, but the only choice 10X10 fits fine on my 10X10 canopy. I don't see any way to adjust it to 8x8.

8x20 are small but good enough for travel etc. for birding I use 8 x42 which gives the best of both worlds but not as compact. You may need to research further for a more accurate answer. Depends on what you intend to use the binoculars for.

I found this video helpful. It's for a 10x30, but the same principles apply. Good luck! http://www.youtube.com/watch?v=cnvJeRXNsoM

Go with an 8x42 or a 10x42. 8x for wooded areas. 10x for open areas. 8x for white tail deer. 10x for mule deer.

Here's a simple test for your question Vlad; 10 X is basically ten times the size of the original object being viewed, so if the numbers are say 2 inches tall they would appear 20 inches tall at the same distance when viewed through 10X bino's.

Sorry i really don't know. I bought it a long time ago. But i know it does fit a 10x20 perfectly.

I do not know exactly. I tried to use them on a 31x10.5x15 and they were too small. I have never used my set

There are different sizes to choose from, mine were different size rectangle, but I believe there is a square for 52X52.

I can't answer this. I have not been to Alaska ;). The only thing about these is the 10X42 the 10 is so tight that the slightest movement the object will "move" might try the 8X42s Have fun in Alaska. Betty W.

If you order 60"x24" that's what you get. I have ordered several different sizes and always got what I ordered.

No 10x10 only. Its worth getting the 10x10. This mesh wall kit is great. I've had mine fore 2 years now and its still holding up great. I use it a lot.

sorry gave as a gift I cant measure. 5x5 x3x5x13.8 is listed under item details. I believe that was correct.

It looks like the difference is in the size, take a look at the product dimensions of each and you'll see what I mean.

I was told to use the 22X22X5 and I just measured my bal leveler and I would have to agree with that advise. That is what I am ordering today.
