[How to recover]

When the Err 70 occurs, please turn off the power and put it on again or remove and insert the battery.

[How to reduce the frequency of errors]

Occurrence conditions differ depending on the model, but an error is more likely to occur when setting high-speed continuous shooting, small aperture, and high-speed shutter speed

Please try changing the camera settings as below.

  • Set the drive mode to "single shot"
  • Set the aperture to the open side or the shutter speed to slower.
  • Set to lower ISO sensitivity.

We will continue to work on updating the firmware to match the mentioned cameras with each of the lenses. Please watch for further announcement on updated firmware.

We sincerely apologize to all users and potential purchasers for any inconvenience this issue may cause.
