How can I use a Samsung NX300 on a telescope without getting a “no lens” error?

I want to attach my Samsung NX300 to a telescope using an NX-to-T2 adapter, but the camera won’t shoot and only shows “no lens.” The NX300 doesn’t appear to have a menu option for shooting without a lens, and its manual-focus switch is on the lens. Is there a proper way to make this work with a telescope adapter?

In order for the camera to fire, a small spring loaded connection has to be pushed in far enough.
If you take off the lens and look in the exact opposite direction of the red dot, you will see a small metal point sticking out. That is it.
The challenge is to ensure that the T2 mount you purchase is designed specifically for the Samsung NX range of cameras. Without the correct adaptor, the connection will not be pushed in far enough and result in "no lens" error.
The correct mount will press this connection and you should then be able to use it with any T2 mount lens or telescope. However, this only works in the cameras Manual or Aperture modes.
You can also use some sticky tape to correct this, but that is at your own risk and can cause issues if not done correctly.
Good luck

Yes—an NX300 can work on a telescope, but unlike some cameras it does not appear to offer a normal “release without lens” menu setting. Instead, the adapter must physically depress the small spring-loaded mechanical switch inside the lens mount. If that switch is not pressed far enough, the camera reports “no lens” and won’t fire.
Check that your NX-to-T2 adapter is specifically made for the Samsung NX mount. A correct adapter should press that switch so the camera will operate with the telescope attached. Community reports indicate this works in Manual or Aperture mode.
If your adapter is slightly out of spec, some users improvise a fix to press the switch, but that is at your own risk and could cause damage or other issues if done poorly. In most cases, the real solution is simply using a properly designed Samsung NX adapter.
