Has anyone successfully rigged up this gimbal setup? Currently having quite the time...

Gimbal: Ikan Beholder EC-1 (Holds up to 4.5lbs)

Camera: Sony A7sii (1lb, 6oz)

Lens: Sony Vario Tessar Zeiss 24-70/f4 (15oz)

Additional: Sony XLR-K2M XLR Adapter kit (13.1oz)

Any thoughts or links that might be helpful? I've watched the Ikan setup video but they use a 35/2.8 lens and no XLR mount.

I run with the Beholder DS-1 which is the precursor to the EC-1. I'm betting the lens may be part of the problem. I have that lens and unless you leave it at whatever mm, changing the focal length mandates a recalibration due to lens extending. I typically use the 28 f2.0 on mine although I have used the 18-105 successfully because zoom is internal on that particular lens.


If you have that XLR mic mounted there's a good chance that places the vertical center of gravity outside the limits of adjustability the rig provides. Look to mount mic off camera on the 1/4" post on the handle and either 1) Connect to camera via extension MIS cable long enough to allow movement flexibility or 2) Connect to an external audio recorder. Any connecting cable generally isn't sufficient to throw the gyros into a trembling correction dance trying to compensate a slight balance offset. I have such a cable to trigger recording attached to the handle and have no problem maintaining gimbal balance.

The decisive thing is not the weight, but the  _balance_  of the camera/lense. Those brushless motors cannot provide for an arbitrarily large torque to maintain the direction. The ideal balance is, when the camera maintains horizontal orientation without the gimbal being powered on.


The other thing is mechanical blocking. Even though the gimbal is advertised featuring three 360° motors, mounting anything different from a pancake lense will likely introduce a mechanical block, if you really need 360° of rotation about yaw or pitch axis. (Roll should be fine, regardless of lense length).


A variable-length lense (zoom) is likely to add some off-balance to an initially balanced system, once you engage the zoom. Like @VTC, I would strongly discourage from mounting a micro to a "gimbaled" camera, as this off-center weight is likely to compound both mechanical blocking and compensative torque requirements.

      Hi guys,
      New to the group, recently created this low light test, thought it might be useful for you guys. What do we think?

      I've been having a problem when recording with my Sony A6300.
      The problem is that every time I start recording, it automatically stops at the 20th second.  I've tried to change the settings and see if the problem has to do with that but no, I even bought Sony's sd xc I U3 64GB
       memory card and nothing has changed. I would like to know if somebody else has this problem and how it can be fixed.

      I've been shooting a doc on the a7sii. WB is always set to manual, either incandescent or a kelvin setting. However, at times I'm noticing a strange "strobing" color shift in the footage and it's driving me crazy.
      You can view a 4k sample here: https://bit.ly/2tO5dQh
      The first clip in the above video is at 1600, the record player shot may be 3200. Picture Profile 7. High ISO NR was off I believe, but that should not kick in at 1600, right? It's mostly in the shadows and will switch back and forth a frame at a time ... but only sometimes.
      Anyone experienced this before?

      Hello! I recently bought an A7III and shoot some footage with it but I can't seem to find the location of it on my computer. Where do I go to find the footage?
      Also, I can't preview the raw images I've captured. If I want to see the images, I have to open Lightroom. However, I seem to be having no trouble at all with my a6000.
      Any help will be appreciated!
