I have been using a SmallRig cage with my Nikon Z 50 when recording handheld videos. Unfortunately, the Nikon Z 50 doesn’t use external power via a USB cable unless the camera is off. The Nikon Z fc does, but no one made a cage for it.
The Ulanzi Falcam F22 & F38 & F50 Quick Release Foldable Half Cage For Camera said it works with it and try it I did.
Pico review: it works
I only played with it for an hour, but the Ulanzi foldable half cage worked effectively with the Nikon Zfc. It was pretty sturdy, though not nearly as sturdy as a full cage.
It does not come with a NATO rail attachment point anywhere, so I needed to attach a SmallRig Low-Profile NATO Rail, 50mm to the top of the half cage so I could add my top handle. I was able to move the camera around effectively that way. Ulanzi has their own Falcam enabled top handle so if you don’t have one, you can get theirs and attach it the top Falcam rail point.
There are three Falcam rail points: the top, side and bottom. The top and bottom are side to side. The side rail point is up and down. There are three 1/4 inch screw holes on the top and side and two on the bottom.
Folding and unfolding the cage was easy, and there are points every 45 degrees where you need to use a bit of pressure to rotate the arms. This feature helps since if the arms are not locked, your camera won’t suddenly rotate unexpectedly. The locks were secure, but you can get a little wobble if you don’t turn them completely to the lock position.
The Falcam quick release mount had locked and unlocked position. Only if you pressed it in the unlocked position, would it actually unlock and slide so you could take the camera off the cage. The mount is square and you can rotate it on each side and it will slide in and lock. However, with the FTZ adapter on, I found it more difficult to slide the quick release mount on in one direction, but not another. It should work, so I will play around with it and see what I did wrong.
I recommend it.
