Hey!

I just received my RS2 and installed the focus motor. Is there any way to set a STOP / range in which the motor operates? When i reach the end of the focus range on my lens the motor is not able to spin any further and makes a strange noise. I thought it mit damage the motor.

Hello, thanks for the information. As the lens you used is not on our recommend lens list (you can visit https://www.dji.com/support/compatibility/rs-2/gh5), we have not tested the lens from the Walimex.
We will send this lens info to our camera testing team for reference and we suggest you to use the lens that on the list (see the link above) for the better experiences.

Thanks!

I think you are missing the point here. It has nothing to do with the type of lens or camera I am using.
This issue is present on ALL manual lenses

HI, I also have this issue with any manual lens.  I read that you can set hard stops with the DJI focus wheel.  I bought that and hope it helps, but we should be able to do this without buying extra pieces.

Hi,

I have the same issue using the focus motor.
I would need to set a starting and end point so the focus wheel doesn't force on my lens nor the focus wheel.

Thank you DJI!
The latest update added "Dolly Zoom" which enable calibration of the focus motor.

This is a big problem for me as well. There NEEDS to be a way to manually set the focus end points. The focus motor almost ripped off my camera as it keeps spinning when it gets to the hard stop.  Even if it does calibrate the lense it keeps going past the hard stop and loosening the camera every time.  There is so much torque in the focus motor I’m convinced that it’s probably damaging the mount of my camera. Tried again tonight with the new 3D focus system and it unscrewed a Helios lense when trying to calibrate it was spinning with so much torque once it reached the hard stop.  

PLEASE update in a firmware release DJI!

The focus motor and the new 3D focus are useless without manual calibration or a better dead zone with more sensitive focus motor auto calibration near the hard stops of a lense!!

paul pan wrote (i think will come to the RS-2 also):

RSC2 Beta
What’s New?
•        Added Orbit Follow mode.
•         Added manual setting for focus endpoints for DJI Ronin Focus Motor,  where users can set a controllable range between Point A to Point B  manually.
•        Added Deep  Sleep mode to extend battery power. Press the gimbal power button twice  to enter sleep mode, and the gimbal will automatically enter Deep Sleep  mode after 10 minutes if no interaction has happened with the gimbal.  The touchscreen will be set to its lowest brightness, and the RSA  accessory expansion port will power off. Repeat to exit Deep Sleep mode.
•         Added front dial control over camera parameters, shutter speed, gimbal  tilt/pan movements. Also added adjustable front dial smoothness and  direction reversal.   
•        Added shutter/autofocus control for Z CAM E2、Z CAM E2-F6、Z CAM E2-F8、Z CAM E2-M4、Z CAM E2-S6
•         Optimized roll axes algorithm for large angle tracking in Horizontal,  Portrait, and FPV modes, preventing the gimbal from getting stuck during  tracking at specific angles.
•        Fixed issues: The built-in screen flashes when the gimbal motor is stuck during rotation
•        Fixed issues: calculation error of customized parameters in Panorama mode.
•        Fixed issues: when using Z CAM with manual lenses, the gimbal axes failed to stabilize the camera.

Notes
•        Make sure that the DJI Ronin app is the latest version when updating the firmware.
•         Update the firmware using the DJI Ronin app by connecting the DJI RSC 2  via Bluetooth. Update the firmware of RavenEye transmission module  separately by connecting it with DJI Ronin app via Wi-Fi Do not  disconnect the DJI Ronin app and DJI RSC 2 during the update. Do not  disconnect the DJI Ronin app and DJI RSC 2 during the update.
•         If DJI RSC2 has a camera attached and is powered on while updating the  firmware, make sure to protect the camera and lens as the motors will  power off during the update.
•        If the firmware update fails, restart DJI RSC2 and retry.

So, here we are in 2021, and still have no solution for this?

I'd like to use the focus motor to zoom – the camera should use the AF for focus. As the zoom go he lens has a hard stop, auto calibrating doesn't work, it really puts a lot fo stress to the gear. I' like to simply set the A+B points in the app, or at the RS2 itself, but can't seem to find it.

To anwer my own question in the hope that it helps others:

  • Start up the RS2

If the front dial is not already assigned to control the focus motor:
  • Swipe up the bottom menu
  • > Dial functions
  • Focus Motor
  • Go back to main menu


Now set the limits:
  • Swipe in the right menu
  • Scroll the menu down do the bottom
  • > Set motor endpoints
  • > Manual endpoints
  • Use the front dial to rotate the motor to the start and end points and set start and stop point

But the 3D focus calibration requires automatic focus motor calibration everytime with their twisting plate from the motor calibration  process issue.

I mean the PROBLEM IS UNSOLVED for 3D FOCUS USERS  where the automatic crazy calibration twisting camera on plate and  beating up lenses IS MANDTORY WITHOUT POSSIBILTY TO MANUALY SET POINTS (it requires this even when you set points manualy on Focus Motor).

DJI will this be resolved in future updates?
