1D mark3 firmware on 40D

Has anyone tried booting 1D mark3 firmware on a 40D? The hardware seems to be pretty similar

I don't know how to decrypt 1D mark3 firmware, so I cant try it

They have different sensors I thought, so directly is impossible. And changing them the right way is very hard?

Both have 10.1Mpix effective pixels though

It's worth a try!

Yes but for starters, the AF unit is different. A lot of things may be different, such as memory size, mmio addresses, keys, key 'locations' (memory) and so on. The camera likely won't boot anymore but you're free to try if you can spare one. Also, since the firmware is stuffed with assertions, even if it does boot I doubt it'll run properly.

Some differences which are likely show-stoppers:
- Different cropfactor and sensor sensitivity -> different sensor
- Dual DIGIC III vs single DIGIC III
- Different AF units
- No support for EF-S lenses

plus

different amount of function buttons
1Ds has two card slots, 1 CF and one SD.

The main differences between the software of the 40D and 1D are
- configurable compression ration for the JPG's
- AF Microadjustment

What els do you need/want?

Hello !
I'm a french photographe, and i've been hanging to this forum very intensively ^^
AF-Adjustement on 40D would be crazy !

I haven't any knowledge about how to developp that,
the only thing i can do is telling you that's good to see that some people are working on that thing !
You're my heroes ! ;-)

T keep your spirits up, my main focus is to get AF microadjustments in the 40D.

The FW contains a list of EF lenses which indicates that the software is proably in the firmware. I have located two procedures that (as far as I can see) are not used and that are linkt to AFSHIFT, which I think is AF Microadjustements.

Ik keep on searching
