Review on 🔬 Carson Field Microscope MM-450, Blue, with LED Lighted Zoom and Aspheric Lens System (20x-60x) by John Hill

I bought this for my wife who buys and sells antique silver jewellery. She needs a good magnifying glass to study the stamps and signatures. I am very good at using this microscope, although I have to agree that it is very sensitive, even at full magnification, to keep the object in view. And since you're actually seeing a mirror image of the part you're looking at, you need to take that into account when making adjustments to the part you're looking at. Even the slightest movement of a piece can take what you're trying to explore out of sight, and this is made worse by the fact that you have to move the piece in the opposite direction you think it should be moving. Difficult to explain. I can, but my wife almost gave up because it's too much effort to keep the subject in focus. The focus and zoom wheels are so difficult to turn that it's almost impossible to move both without bringing the subject back into view. I just leave it zoomed out so I never have to touch that setting, and then set the focus dial to "very close" and then move the scope up and down (away from the subject and closer to the subject) just a tiny bit. the subject in sharp focus. You also need to make sure the scope is perpendicular to the subject, as the depth of field is so shallow that even a small piece of jewelry will have sharp focus in one spot and very soft focus in another. Miscellaneous. With a little patience and practice, this can be a great tool. But do the training part before you really need it, otherwise the experience will be frustrating. Aside from the tight, hard-to-turn dials, this is a very nicely made scope, and the built-in light is well placed for illumination. your article. It takes a little getting used to seeing your subject reflected in the mirror, but the clarity of the image is worth the effort in my opinion. For the price, it's a steal too. Also fits in a trouser pocket.
