What else can i do?
:-* Compile with upper lines and test with
EF-S 55-250mm IS STM
EF-M 11-22mm IS STM
If Your superzoom needs more steps zp=31 might be to low.

But I don't know what the zoom steps on the M100 will bring me. The focal length is much more important.

It’s a benefit from a camera with a motor zoom. That is the smallest step size in which I can change the zoom.

 :) Thx!
Probably we need not more precision here. Maybe it helps optimizing some AV-dependent values or compatibility with scripts or their logfiles. A constant 0 value might become boring if we can have senseful 0..37(++?) without risk.
Implementing focus is much less trivial. (How to name the addresses on low level, where to define...)

Re: A way to get_zoom() on EOS-M 100

In the first approach I would use an average get_focus_distace_upper and get_focus_distace_lower (from M3M10M100_Focus.lua) for the focus.
"Downside"  :-X it would look somehow(!!) like this: Probably not very satisfying with higher zoom or near infinity.
Code: [Select]
int   shooting_get_exif_subject_dist()          {
if(conf.platformid==13009) //  Edit:  Compiler warning, added  2*(   )
return (((unsigned short) *(unsigned short *)(0x001FC7FA)>>1)+
((unsigned short) *(unsigned short *)(0x001FC7FC)>>1));
return shooting_get_prop_int(PROPCASE_SUBJECT_DIST1); }


short shooting_is_infinity_distance()
{
  if (conf.platformid==13009) return ((unsigned short) *(unsigned short *)(0x001FC7FA)>65432)?1:0;
  return (shooting_get_lens_to_focal_plane_width() == 0)?1:0;
}

Based on the upper lines and ::) replacements
Code: [Select]
// console.c
#ifdef CAM_ILC // Eos-M
#define MAX_CONSOLE_HISTORY     100
#else
#define MAX_CONSOLE_HISTORY     30
#endif
// * /-------------------------------------------------------------------
static void save_console()
{
    FILE *fh = fopen("A/console.Log","wb");
    if(!fh) return;
short i=0;
static char const *c; c=&console_buf[0][0];
//        fwrite((char *)&console_buf,sizeof(console_buf),1,fh);

while (i<MAX_CONSOLE_HISTORY*(MAX_CONSOLE_LINE_LENGTH+1))
{
while (*c=='\0') { c++; i++;}
while (*c!='\0') {fwrite((char *)c,1,1,fh); c++; i++;}
fwrite((char *)"\n",1,1,fh);
while (i%(MAX_CONSOLE_LINE_LENGTH+1)!=0) {c++; i++;}
}
    fclose(fh);
}
//-------------------------------------------------------------------* /
    case KEY_LEFT:
save_console();
        break;

Code: [Select]
                     // scale by users adapter lens eg. Canon Wide .42 or Canon Tele 1.75
                     fl = fl * conf.zoom_scale / 100;    //  gui_osd.c line...404
Could be best place for this lines in main.c, shooting.c, luascript.c & ubasic.c or in script?
How to find out ?
Do we need to feed missing values or tables with script?
Knows cam if -M or -EF is attached?
