{"product_id":"80mm-front-ring-extension","title":"80mm Front Ring - Extension","description":"The 80mm Front Ring - Extension is a unique solution for lens setups that require a bit more space between the filter threads of the lens and the matte box or filter attachment. Available in several sizes, the 77-77mm models will essentially extend a plain 77mm filter thread by 1\" or 2\". The 60-77mm x 0.5 model is ideal for use with the Leica R 35-70mm f\/4.0 lens which requires a slightly longer step-up ring in order to accommodate full focus and zoom travel. Machined from billet aluminum and anodized black with a threaded inside surface to reduce reflections.","brand":"Duclos Lenses","offers":[{"title":"77-77mm x 1\"","offer_id":56210162417969,"sku":"38208057","price":95.0,"currency_code":"USD","in_stock":true},{"title":"77-77mm x 2\"","offer_id":56210162450737,"sku":"38208056","price":125.0,"currency_code":"USD","in_stock":true},{"title":"60-77mm x 0.5\"","offer_id":56210162483505,"sku":"38208360","price":95.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0851\/8703\/5441\/files\/77mm-1in-extension-hood.png?v=1789049509","url":"https:\/\/www.impulsecameras.com\/products\/80mm-front-ring-extension","provider":"IMPULSE","version":"1.0","type":"link"}
