SmallRig 3940 Reviews

Stupid Design Flaw

By Wild
Rated 2 out of 5
Date: 2025-04-27

I own several of these for other cameras, and use them for low angle photography with a monopod attached to the top of the cage. The others I have fit perfectly and allow full use of all camera functions. With this one there’s a major flaw for my purposes - Smallrig have made the vertical part of the cage on the left front too big to allow the secure attachment & use of the Nikon MC-30 10-pin remote trigger. You’d have to take a file or Dremel grinder to remove a part of the cage, and then repaint the ugly wound you end up with.

Great Fit

The cage is a great fit for the Z8, it also allows for extra protection. Love the tool compartment at the bottom.

With the cage fixed onto the Z8, will that allow mounting the camera on a tripod in portrait orientation?
Asked by: Zon Hisham
Yes, because the SmallRig Camera Cage for Nikon Z8 has 1/4"-20 threads on both sides of the cage, the cage can be mounted to a tripod in both landscape and portrait orientations.
