One of the most appealing aspects of small mirrorless cameras like the Sony FX3 and A7IV is the availability of a wide range of interchangeable lenses, including non-Sony lenses. This Novoflex Adapter for Canon FD Lens to Sony E-Mount Camera makes it possible to mount a Canon FD lens to your E-Mount camera with a precision mechanical adapter. Such an adapter does not transfer functions from the camera to the lens, such as auto focus, but automatic exposure metering (stop-down metering/aperture priority) is possible. The lens will focus to infinity using this adapter.
