{"product_id":"bower-sx7dgc-2x-teleconverter-for-canon-7-element","title":"Bower SX7DGC 2x Teleconverter for Canon (7 Element)","description":"The 2x DGII Teleconverter (7 element) for Canon uses upgraded multi-coated optics to double the focal length of the existing lens.  Using the 2x DGII teleconverter with an 85mm f\/1.4 lens, for example, will double the focal length to 170mm, which effectively sets the maximum aperture at f\/2.8 (cutting the amount of light captured). Also known as a tele-extender, it serves as an excellent lens modifier that is portable, high-quality and versatile. The lens used must have a maximum aperture greater than f\/4.0 in order to fully utilize its autofocus capabilities.\n\n\u003cbr\u003e\u003cbr\u003e","brand":"Bower Camera","offers":[{"title":"Default Title","offer_id":48600288133335,"sku":"SX7DGC_sses","price":139.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0792\/4003\/6567\/files\/139267.jpg?v=1780500921","url":"https:\/\/ssephotovideo.com\/products\/bower-sx7dgc-2x-teleconverter-for-canon-7-element","provider":"Ssephotovideo","version":"1.0","type":"link"}
