The higher the magnification, the closer the focal length and the smaller the field of view. As magnification power increases, you work closer to your subject and see a smaller area in focus. A 10X loupe offers the highest magnification with the closest focal length and smallest field of view. A 3X loupe offers the lowest magnification with the furthest focal length and the largest field of view. At 4X, this loupe provides a balance of magnification and working distance well suited for general watchmaking and jewelry inspection tasks.\u003c\/p\u003e","brand":"Otto Frei","offers":[{"title":"Default Title","offer_id":43584417890518,"sku":"129.622","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-4x-otto-frei-1.jpg?v=1719956203","url":"https:\/\/www.ottofrei.com\/it\/products\/single-lens-watchmakers-loupe-4x","provider":"Otto Frei","version":"1.0","type":"link"}
