Review on 📸 Neewer AF Auto Focus Macro Extension Tube Set 10mm 16mm Compatible with Sony E-Mount Lenses, Maximum Load: 500G by Chris Wheeler

DID NOT WORK with Sony a7r3 and 24-70mm GM. If you're looking for extension tubes, spend an extra $10. The item arrived quickly and well packaged, but unfortunately didn't work that well. They fit on the E/Lens mount, although the camera loses connection every 30 seconds without knowing it has a lens and I would get F/-- and lose the aperture/autofocus functionality. I then had to turn off the camera, shake the lens because the extension tubes weren't 100% tight, turn on the camera and pray to the gods at Sony that I get a few more seconds of use before that little spider I found start moving again. I probably have > Made 20 times before giving up cheap plastic tubes and opting for a refund. They don't appear to be broken or anything, just not good enough to carry around a beefy 2lb lens. I can advise you to go to the gym.
