Hello everybody,
it looks like EOS M3, M5, 5D MkIV and maybe 80D and 1D-X MkII can
get lens correction data in three different ways:
1) Included in onboard firmware
2) Uploaded vis EOS Utility
3) Delivered onboard newer lenses
Can anybody shed a light on the format of these correction profiles?
In another discussion elsewhere a user reported the Sigma 150-600
Contemporary to be recognized by his 5D MkIV in full text.
Maybe this lens doesn't make use of a fake lens ID anymore,
rpvided that the camera supports lens profile loading from the
lens itself.
This opens new possibilities in correcting uncoupled "dumb" lenses
inside the camera by maybe building a module loader for extra profiles.
I am not a programmer, just a user with sometimes wild ideas.
Does that make any sense?
Regards, Michael
