SmallRig MD4019 Reviews

Does not work for a1ii

By Ryan

It’s a cool piece. I was hoping it would work to get the fx3 handle onto the A1ii with the small rig cage. But it’s like a hair off if you have a milling machine you could make it work. Too bad.

The central screw needs to be removed when using this adapter with A7RV, but the two side screws are strong enough to make you feel confident about carrying the whole rig by the handle. A clean, compact setup for using an XLR mic like the Sony ECM-MS2.

Will this fit on cage 2918 for the A7iii?
