10X is more practical. Jun 08, 2010 The 10X Belomo is terrific. 20X is for specialized use, like trying to identify forams in the field when you can't carry a stereo microscope.
Fantastics Loupe!! Apr 20, 2010 I bought this loupe after I purchased my wife's engagement ring. I was a bit undecided on whether to buy the 10x or the 20x but am completely satisfied with the 20x. The 20x magnification is great for reading the laser inscription on the girdle of my wife's stone. The build quality of the loupe is also excellent. Though small, this loupe feels very solid in your hand. When unfolded your index finger slips nicely into the case allowing for comfortable viewing. If you're considering this loupe keep in mind you will need to be able to bring the object you're viewing very close to the glass in order for your subject to come into focus. Overall, very satisfied. Highly recommended. Great product.
20x loupe Apr 02, 2010 I now have the Belomo 10x and 20x folding loupes. They both serve a purpose. I strongly agree with reviews that the 20x is POWERFUL. The 10x will serve most people's needs. The 20x allows for very little eye relief and you have to almost touch the object in order to pull focus. Most importantly, you need a lot of illumination in order to get a good view. Keep that in mind. Anyway, they are both very good especially for the money. If you're not sure which one you need, my suggestion is get them both!

Ok Jan 04, 2010 Works ok. Probably works better outside in the sunlight. Not so great indoors. Not so great if you're unable to move object closer to face for inspect. Would be nice if it had some LEDs to help illuminate item.

Way too much magnification Sep 01, 2009 OK, this is a great medium quality magnifier. The optics of the BelOMO are considered to be some of the finest. BelOMO is the Belarusian Optical Manufacturing Association. Back in the cold war days they were the optical company for the Soviet Union. They make cameras and lenses, telescopes, and all types of optical products including bomb sights and tank sights.
Each BelOMO magnifier is manufactured as an quality optical lens. In the box you'll find the specification sheet (OK, it's in Russian but there's an English version available on the web)and each sheet bears the optical inspection stamp. You won't find other magnifiers in this price range that are certified to pass inspection just like a camera or telescope.
So, if you need 20x times magnification you can't go wrong with this magnifier.
BUT....... do you really need 20x magnification. I don't think so!
A lot of first time buyers think that more magnification is better. Not true. The appropriate magnification is better.
For most cases this means a 10x magnifier. Plenty of magnification and gathers plenty of light for a bright and sharp image. Start with a 10x.
If you're trying to look at extremely small objects then a 20x may be the proper magnification for you. For instance, if you need to inspect the edge of a razor or a knife blade this could be the magnifier for you. If you're trying to read the laser inscription on a diamond then this might be the loupe for you. If you need to closely inspect individual hairs or the pores of the skin, this could be the magnifier for you.
Let's compare using 3 of the BelOMO magnifiers while looking at a quarter (which is about an inch across): the 7x, 10x and the 20x.
If you're like me looking at a quarter as close as you can you'd probably find that you are holding it about 8 inches from the eye.
The 7x would let you get about 7 times closer to quarter or about an inch and a half away. You'd be holding the loupe, as with all loupes, almost touching the eyelid lashes and holding the quarter about an inch and a half away from the front of the loupe. Using the loupe your eye is now able to focus on this quarter and see much more detail since it's an inch and a half away.
Take the 10x. It would let you get about 10 times closer to quarter or just about an inch away. You'd be holding the loupe, as with all loupes, almost touching the eyelid lashes and holding the quarter about an inch away from the front of the loupe. Using the loupe your eye is now able to focus on this quarter and see much more detail since it's only an inch away.
Now take the 20x. The 20x will let you get about 20 times closer to quarter than your eye can normally focus. You're only about 3/8 of an inch away. You'd be holding the loupe, as with all loupes, almost touching the eyelid lashes and holding the quarter would be almost touching the front of the loupe. Using this loupe your eye is now able to focus on this quarter and see much more detail since it's so close to the eye.
Consider the depth of field which is the vertical relief of an object that appears to be in focus.
Say you're looking at the back of your hand with a 7x loupe. The hairs and the skin would appear in focus.
The same pretty much holds for a 10x loupe. The hairs and the skin still seem to be pretty much in focus.
Using the 20x loupe you one part of the skin would appear in focus. Or if you're looking at a hair a small part of the hair would appear in focus but focus would rapidly fall away on either side of the part of the hair you were focused on.
Even on a quarter there's almost enough vertical relief between the face and the background that when you're looking at the face the background is slightly fuzzy.
So, make sure you really need this strong of magnification before you order this loupe but if you do need it, then choose this loupe.
