Its innovative floating element system, developed through years of dedicated optical research, virtually eliminates aberrations across the entire zoom range while delivering notably high sharpness and image brilliance for a lens of this scope. A push-pull zoom and focus mechanism sets it apart from the two-touch designs common among competing super-wide zooms, and its close-focusing capability extends creative versatility well beyond standard wide-angle use. Offered across nearly every major manual-focus SLR mount of its era, this pioneering Sigma zoom remains a historically significant and highly capable lens for architecture, interior, and expansive landscape photography.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"flow-root\"\u003e\n\u003cdiv\u003e\n\u003cdiv class=\"ml-1 mt-6 flex items-center transition-transform duration-300 ease-out\"\u003e\n\u003cdiv class=\"p-1 -translate-x-px\"\u003e\n\u003cdiv aria-hidden=\"true\"\u003e \u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv aria-hidden=\"true\"\u003e \u003c\/div\u003e\n\u003cdiv class=\"h-px w-full pointer-events-none\" aria-hidden=\"true\"\u003e \u003c\/div\u003e","brand":"Sigma","offers":[{"title":"Default Title","offer_id":42629829197870,"sku":"USESIGZOOT2135F35-U8","price":349.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2657\/1868\/files\/d515a3d9-8390-4f17-9ce9-0bbea74e6d14.jpg?v=1786466101","url":"https:\/\/kmcamera.com\/products\/usesigzoot2135f35-u8","provider":"K\u0026M Camera","version":"1.0","type":"link"}
