Firmware Changes

Firmware Version 1.2.0 incorporates the following improvements.

  1. Supports the WFT-E2 II wireless file transmitter that was released in December 2009

Firmware Version 1.2.0 is for cameras with firmware up to Version 1.1.4. If the camera's firmware is already version 1.2.0, it is not necessary to update the firmware.

In addition, after the firmware is updated, if the WFT-E2 / E2A or WFT-E2 II wireless file transmitter is used with the camera, the indications that appear under [Communication mode] on the [WFT settings] menu are changed as follows:

  • FTP -> FTPtrans
  • PTP(PC) -> EOSUtility
  • HTTP -> WFTserver
  • HTTP account -> WFT account

If you are setting the WFT-E2 II by using a computer, please download and use the dedicated WFT Utility application.
For details on how to download WFT Utility, please go to the software download pages.

Before downloading the firmware update, please be sure to read the entire contents of this page.
