Any todo or something for E1.100b,Ix500HS.100e or Sx600.100c?
(Call me from port)

No, I didn't do anything with these cameras, and although the ixus 500 looks interesting, it's a really really old digic5 camera.

A thought based on Ix1000,

It doesn't matter what other cameras use, look what's in the firmware.
#define NUM_DATA 2 tells how focal lengths are represented in the firmware table.
2 means that each focal length is displayed in two words. For this camera, it looks like this:
