what exactly needs to be "fixed"?
This comes to mind (ask me again when my 6d arrives :-p)
- Multipoint af servo not properly handing over focus from one point to the others, esp. not selecting the center point (CarlTN keeps mentioning this)
- Braindead crippling that hdr source files cannot be saved
- Crippled min. shutter in av (1/250s is the fastest? Canon, you gotta be joking! Hail to ML!)
- Crippled feature -> button allocation vs. 5d3
- GPS off on power down, auto-enable on power up
