Another firmware update from Canon fixes a few problems but doesn’t change any major features of the camera. For those using UDMA 7 CF cards, you may be happy to see some increased speed.
1. Improves writing/reading speeds when using UDMA 7-compatible CF cards.
2. Fixes a phenomenon where the IS function will not work when custom function C.Fn III-2 is set to [5: IS start] and the lens attached does not have an AF stop button. This is because custom function C.Fn III-2 allows users to assign IS start to the AF stop button on the lens
3. Corrects misspellings in the menu screens displayed in Arabic, Portuguese, Spanish, and Thai languages.
