Review on Ade Advanced Optics Chelsea Testing by Kelsey Brown

This is my first Chelsea filter so I have no comparison. Overall I really like it and have used it to test some of the gems in my collection. The only thing that frustrates me personally is that it's very blurry when you try to look at it like you would through a magnifying glass. I have to hold it at a distance (about 4 to 6 inches from the eye) to see the gem clearly, but then I wonder if I'm seeing the gem's color properly through the lens since it's relatively far away. But like I said, this is my first camera so I'm not sure if they're all blurry up close. So far I'm glad I have it and enjoy using it!
