What has changed in Firmware Version 1.2.4?

The following fixes and improvements have been incorporated.

1. Supports the WFT-E4 II wireless file transmitter that was released in December 2009.


2. Corrects a phenomenon in which visible noise may appear in images taken by continuous Bulb shooting.

This firmware update corrects a phenomenon that if the [C.Fn II-1 Long exposure noise reduction] setting is set to [2: On], noise may appear in images that are captured while the previous image is still being generated.
