Designed especially for cameras with a Super 35 sensor, the adapter helps maintain the original field of view of full-frame EF lenses while providing greater flexibility for professional cinema and video production.\u003c\/p\u003e\n\u003cp\u003eUnlike a conventional lens mount adapter, the EF-EOS R 0.71x incorporates an integrated optical system that increases the effective angle of view by \u003cstrong\u003e0.71x\u003c\/strong\u003e. This helps reduce the crop normally experienced when using a full-frame EF lens on a Super 35 sensor, allowing cinematographers to achieve a field of view closer to the lens's original full-frame perspective.\u003c\/p\u003e\n\u003cp\u003eThe optical design also improves maximum aperture performance by approximately \u003cstrong\u003eone stop\u003c\/strong\u003e, providing increased light transmission when shooting with compatible EF lenses. This can be especially useful for low-light production and situations where maintaining a shallower depth of field or maximizing available light is important.\u003c\/p\u003e\n\u003cp\u003eBuilt-in electronic contacts maintain communication between compatible Canon EF lenses and the camera. This enables supported functions including \u003cstrong\u003elens metadata transmission and Dual Pixel autofocus\u003c\/strong\u003e with select Canon EF lenses, helping retain important electronic functionality while adapting lenses to an RF-mount camera.\u003c\/p\u003e\n\u003cp\u003eThe adapter has been specifically designed for use with the \u003cstrong\u003eCanon EOS C70 cinema camera\u003c\/strong\u003e.
