Just saw this on twitter. An anonymous donor gave a 7D to Hudson. While you might be thinking “So what? I have a 5DMrkII!” and even be a bit frustrated to know the 7D might take some time away from Hudson to work on the 5DMrkII, this could be in fact a good news.
Quoted from the Magic Lantern site FAQ when asked about if it would be possible to add 24p to the 5D:
Additionally it might be possible to read the firmware in the 7D or 500D/T1i to see how the different frame rates are selected and to program the DIGIC4 in the 5D Mark II with the same values to see if it works.
Only time will tell.
