A:Answer Yes, you can use a specific adapter to mount your Nikon 35mm lens on the Sony Alpha a7 III Mirrorless 4K Video Camera. Since the Nikon lens has an F-mount, you'll need a lens adapter that allows you to use Nikon F-mount lenses on Sony E-mount cameras like the Alpha a7 III.
There are several third-party manufacturers that produce high-quality lens adapters for this purpose. Look for a Nikon F to Sony E-mount adapter that has good reviews and is compatible with the Alpha a7 III. These adapters are readily available online or in camera accessory stores.
