Can I adapt the zeiss milvus 50mm f 1 4 to sony e?
The Zeiss Milvus 50mm f/1.4 page lists only two mounts: Canon EF and Nikon F. Sony E isn't among them, so I can't tell you from this site that it works on a Sony body, adapted or otherwise.
The adapters section explains that mirrorless mounts are shallow, so old manual-focus film lenses adapt easily and cheaply. That's the general idea, but it doesn't mean every lens adapts to every mirrorless body. The Milvus is a modern lens, and I'd check its specifics with the maker before buying an adapter.
If you want a fast 50mm for Sony, the portraits guide calls the 50mm f/1.8 the cheapest great lens in photography, made for almost every mount. It's a sensible place to start.
