Leica SL3/SL3-S camera firmware update version 4.0.1 released

By LR admin | Published: March 17, 2026


Leica Camera released a new firmware update version 4.0.1 for the Leica SL3 and SL3-S cameras with two improvements:

  • When the focus mode was set manually (MF) in video mode, autofocus was not available via the joystick. AF activation via the joystick is now possible again.
  • An error in bulb mode has been corrected, whereby a long exposure that could not be canceled was started after delayed activation of the first and second pressure points of the shutter release. Bulb mode now works correctly.
