FotodioX EXCL1-CY-MFT-PRO Overview
Enabling the use of your Contax/Yashica-mount lenses on a Micro Four Thirds camera body, this Excell+1 Lens Adapter from Fotodiox additionally helps to increase the effective maximum aperture of your lens, gain a wider field of view, and maintain infinity focus. By incorporating a light focusing optic into this adapter's design, a magnification factor of 0.72x is applied to render a 50mm focal length lens as a 36mm lens, which then provides a 72mm equivalent focal length in conjunction with the Micro Four Thirds crop factor. This optic also condenses light in order to gain an additional stop of light, which effectively renders your f/2.8 lens as an f/2 lens.
The adapter is constructed from brass and features stainless steel finishing, and a leaf spring design is used to secure the lens in place and to ensure no play between the lens, adapter, and camera body. The adapter is fully manual and does not transmit any electronic functions between the lens and camera, and requires stop-down metering for use.
