Correction of review "When reading fine letters such as instructions"

○ Good part · It is the same as the last post, but add "I can see very well for the price". I will make five stars. ○ Bad places: Correcting · · · Usage was incorrect. I'm sorry. (I think it is necessary to describe how to use it in the manual.) · I wrote that "There is considerable large chromatic aberration and pincushion type distortion aberration", but I withdraw it. There is a back side of the lens, and when using with one piece, if you use the lens closer to the eye, you will not be bothered by chromatic aberration and distortion of pincushion type. It looks sharp. If you use it face down, these will become big. · When using with 3 lenses, these aberrations will increase as expected, but using 3 sheets is a time to read very fine letters, so there is no need to see such a wide range, there is no problem.

○ Good part · Large lens diameter and wide field of view, so easy to see · Light · Easy to use · Easy to use · Easy to use · Lens 1, 2 or 3 lenses can be selected · Distance with the object and eyes Easy to adjust distance, easy to use · Low price ○ Bad places · Large magnification chromatic aberration and pincushion type distortion aberration are present. I do not feel it much with one lens, but in the three pieces it is only in the center of the field of view that is practical. This is where it does not reach the expensive loupe. · Contrast lowers with 3 lenses

To see the state of the product under processing or to see scratches, this price this precision. enough. Also, although it is not enough to wear glasses, it is also useful when a presbyopic person sees drawing tolerances.

Three sheets of loupes, one on 5X, but the distortion in the periphery against the focus is severe in the center, the field of view is extremely narrow. It seems to be due to the distortion of the lens, but it can not be said that it does not become usable at all as 15 × piled up. On the backside of the item is displayed as china. Hope to exchange to another company's product.
