The relationship between magnification, focal length, and field of view is important to understand when selecting a loupe. As magnification increases, focal length decreases and the field of view becomes smaller — meaning you work closer to your subject and see a narrower area in focus. At 10X, this loupe provides the highest magnification in the single-lens range, with the closest focal length and the smallest field of view. If a wider field of view or greater working distance is needed, a lower-magnification loupe (such as 3X) would be more appropriate for that task.\u003c\/p\u003e","brand":"Otto Frei","offers":[{"title":"Default Title","offer_id":43584416317654,"sku":"129.619","price":2.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0609\/9832\/0342\/files\/single-lens-watchmakers-loupe-10x-otto-frei-1.jpg?v=1719956205","url":"https:\/\/www.ottofrei.com\/ja\/products\/single-lens-watchmakers-loupe-10x","provider":"Otto Frei","version":"1.0","type":"link"}
