The Record menu has three settings under Converter: (1) WC-DC58B, (2) TC-DC58C, (3) none.
I have the WC-DC 58B, and (except for its size and weight) really love it. But it's a pain to have to set the Converter menu, then set it back to none when I revert to normal shooting. And why bother? There is no difference in the recorded image, no matter what the setting selected.
I've searched the Forum for an answer to this recurring question. Nobody seems to know what the Converter settings actually do. The Canon manual gives no clue.
So I thought I'd start the thread again, this time with a title which should be a magnet for future discussions of this topic. Somebody must know the answer.
The question also pertains to the A-series cameras, such as the A570. This also has the Converter menu.
