Q: 4. Will this work with the Sony a7III?

A: Yes, the FotodioX Macro Extension Tube Set for Sony Alpha E-Mount Cameras: for Extreme Close-Up Photography, B&H # FOMACROTUBSN, would be compatible for use on the E-mount used on the Sony Alpha a7 III Mirrorless Digital Camera. Do note that the above are fully manual extension tubes, as there are no electronic contacts on the lens to transmit electronic information from the lens to the camera. As such, you will have to focus manually, as well as set your exposure manually. You also would not be able to control the aperture of the lens, so you will have to use the camera in either A (Aperture Priority) or M (Manual) mode.

Q: 10. Is this an autofocus?

A: No, there is no communication between the tubes and lens/camera. Auto-focusing while using extension tubes is a lesson in futility, it just won't work. Manual focus is the only way to go when shooting extreme macro.
