The blisteringly fast Sony A9 camera supports both FTP and FTPS file transfers from its built-in Ethernet port. From the product specifications section:
“Using a new terminal for wired LAN connection, you can conveniently transfer still image files to a specified FTP server for viewing and management as needed. A wired LAN connection gives you the highest possible transfer speeds for large image files — an ideal solution for studio photography. Moreover, since FTPS (File Transfer Protocol over SSL/TLS) is supported, image files can be encrypted with SSL or TLS while being transferred, assuring a higher level of security.”
This makes the Sony A9 the third camera and the first non-Canon, that I know of that supports FTP Secure file transfers. It’s unclear whether FTP and FTPS transfers can occur over the built-in Wi-Fi. If not, photographers can purchase a small router like the GLI Inet travel routers that I have been using to securely transfer photos from the camera.
