The single biggest reason to buy is reliable electronic communication: this adapter transmits EXIF data, supports aperture control from the camera, and includes a built-in aperture motor so most lenses behave as expected on RF cameras. It is best suited to stills shooters who need preserved functionality and a sturdy mount without paying professional prices.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Lets Canon EF and EF-S lenses mount to Canon EOS R, RP, R5 and R6 series mirrorless bodies while preserving electronic connections.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAF function \u0026amp; Aperture Control:\u003c\/strong\u003e Built-in aperture motor and electronic contact allow aperture adjustment from the camera body for working lenses that require electronic control.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEXIF signal transmitting:\u003c\/strong\u003e Gold plated pins transmit focal length and exposure data to the camera so lens information is recorded in images.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuilt-in IS Stabilization:\u003c\/strong\u003e The adapter includes stability support to help keep focus steady and produce clearer still images with stabilized lenses.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial \u0026amp; Design:\u003c\/strong\u003e Zinc-plated alloy construction and a 1\/4 in screw mount provide a solid feel and the option to attach a tripod foot for better balance with heavy lenses.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis adapter is for photographers who own Canon EF or EF-S lenses and recently moved to an EOS R mirrorless body but want to keep using legacy glass with electronic control.
