Its 0.71× optical reduction also concentrates more light onto the sensor, giving you approximately \u003cstrong data-start=\"4258\" data-end=\"4303\"\u003eone additional stop of light transmission\u003c\/strong\u003e. That makes it particularly useful when adapting fast Canon EF glass for low-light filmmaking, fashion work, commercials, and documentary shooting. Unlike a basic mechanical adapter, it maintains electronic communication between compatible EF lenses and the RF-mounted C70, including autofocus, iris control, lens metadata, and certain optical corrections. Canon also released firmware updates adding functionality for a range of EF and EF Cinema lenses, including several CN-E primes.\u003c\/p\u003e","brand":"Canon","offers":[{"title":"Default Title","offer_id":42702913470510,"sku":"USECANMOUADAEFEOSR071XBLA-U7","price":149.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2657\/1868\/files\/ea77e1ac-f75c-4f80-a048-56376933d39a.jpg?v=1789166822","url":"https:\/\/kmcamera.com\/products\/usecanmouadaefeosr071xbla-u7","provider":"K\u0026M Camera","version":"1.0","type":"link"}
