Compared to the current Version 1.0.4., the new Changes in the firmware:
We are planning to incorporate the following changes to enhance functions.
- Wi-Fi adapter W-E1 (B&H Photo Video/ Adorama/ Canon Direct Store) will be supported.
- A setting will be added to enable or disable automatic storage of the lens if it is extended out when a gear-driven STM lens*1 is attached, and the power switch is turned to [OFF].
*1 EF 40mm f/2.8 STM, EF 50mm f/1.8 STM, or EF-S 24mm f/2.8 STM lenses
- Lens optical correction data for the EF-S 18-135mm f/3.5-5.6 IS USM lens will be added to the camera.
This firmware update should be available no later than the first week of September.
