It has improved the following phenomenon that occurs when lenses that are not compatible with the MC-11 are attached and no light is emitted on the MC-11’s LED lamp.

  • It does not operate properly on continuous shooting mode.
  • In the case of some lenses that incorporate an OS function, when the camera’s power is turned off, it does not respond to any operation for a certain period of time.
  • When open aperture is not selected for shooting, the aperture does not return to fully open.

※ Improvements may not be visible with some products.
※ The phenomenon that the diaphragm closes when the camera’s power is turned off is due to the characteristic of the camera and is considered to specification.
