Firmware Changes

This firmware update (Version 2.0.0) supports the EOS 50D Digital SLR Camera. If you are using the EOS 40D, you do not need to update the firmware.
If the firmware of the WFT-E3/E3A is Version 1.0.0, the WFT-E3/E3A will not operate in conjunction with the EOS 50D (a firmware update message will appear).
In addition, if the WFT-E3 has the new Version 2.0.0 firmware, it can be used with the EOS 40D as well as the EOS 50D ; however, the three new functions of the Version 2.0.0 firmware below only apply to the EOS 50D ; they do not function on the EOS 40D.

New functions of the new Version 2.0.0 firmware

  1. Supports Wi-Fi Protected Setup
  2. Can transfer images in folders
  3. Can change HTTP port numbers

Version 2.0.0 firmware is for WFT-E3/E3A units with firmware up to Version 1.0.0. If the firmware of the WFT-E3/E3A is already Version 2.0.0, it is not necessary to update the firmware.

Updating WFT-E3/E3A firmware requires a corresponding model of cameras.

*For details on these firmware changes, please download and read the instruction manual at the bottom of the page.


Q: The firmware of the WFT-E3/E3A is Version 1.0.0, so can the WFT-E3/E3A be used with the EOS 50D?

A: It cannot be used with the EOS 50D. Version 1.0.0 only supports the EOS 40D. To use the WFT-E3/E3A with the EOS 50D, it is necessary to update the firmware of the WFT-E3/E3A to Version 2.0.0.


Q: If I have updated the firmware of the WFT-E3/E3A to Version 2.0.0, can the WFT-E3/E3A still be used with the EOS 40D?

A: Even if you have updated the firmware, you can use the unit as is. However, the new functions of Version 2.0.0 firmware that support Wi-Fi Protected Setup, folder image transfers, and HTTP port number changes are not available for use with the EOS 40D. These functions are only available with the EOS 50D.


Q: What is meant by compatibility with Wi-Fi Protected Setup?

A: If your routers and access points support Wi-Fi Protected Setup, the wireless LAN setup process is simplified and you can easily connect the transmitter to a wireless LAN. For connection procedures, see the WFT-E3/E3A instruction manual.


Q: What is meant by transferring images in folders?

A: Images on the camera can be selected and transferred by folder.


Q: What is meant by changing HTTP port numbers?

A: This function allows you to select one WFT-E3/E3A unit that you want to operate from among multiple WFT-E3/E3A units that are connected to the Internet. By allocating different port numbers to different WFT-E3/E3A units, the WFT-E3/E3A unit with the port number specified by the computer is connected. For information on how to make the HTTP settings, see the WFT-E3/E3A instruction manual.


Q: How do I check the WFT-E3/E3A's current firmware version number?

A: Connect the WFT-E3/E3A to the camera, and then turn the camera on. Press the camera's <MENU> button to bring up the "Function Settings 1" item in the menu. Rotate the Quick Control Dial to select "WFT Settings" in the area below. If you press the <SET> button, "WFT Firmware Ver. X.X.X" appears in the area under the display. The number shown there is the WFT-E3/E3A firmware version.
