No sv doesn’t work  :(
But the focal length is still OK. At this time, I used my adapted EF-S 10-18 on 10mm and 18mm.
And the values in the log file are correct. Great job!!!  :) :)
Where does this information come from?

Now PROPCASE_SV and PROPCASE_SV_MARKET are equal to G7X.
You better should ask reyalp about it.

All that I found in firmware according Sv is:
Code: [Select]
loc_FC099EDE
      LDRSH.W R0, [SP,#0x20+var_18]
      MOVS    R2, #2
      ADD     R1, SP, #0x20+var_1C
      STR     R0, [R4,#(dword_1258EC - 0x1258E0)]
      MOVS    R0, #0xFF
      BL      GetPropertyCase_NOEP
      LSLS    R0, R0, #0x1F
      BEQ     loc_FC099EF6
      ADR     R0, aErrorGetsvresult ; "\n\rError : GetSvResult"
      B       loc_FC099F0C
; ---------------------------------------------------------------------------

loc_FC099EF6
      MOVS    R2, #2
      LDRSH.W R0, [SP,#0x20+var_1C]
      MOV     R1, SP
      STR     R0, [R4,#(dword_1258F0 - 0x1258E0)]
      LSLS    R0, R2, #7
      BL      GetPropertyCase_NOEP
      LSLS    R0, R0, #0x1F
      BEQ     loc_FC099F16
      ADR     R0, aErrorGetsvfixresult ; "\n\rError : GetSvFixResult"

Previously I was using modified function EFLensComGetFocalLength, because M3 firmware doesn't contain GetLensCurrentFocalLength function.

But it's present in M10 firmware. So now I use the function equal to one of subfunction called from GetLensCurrentFocalLength  on M10.

What’s about the ISO Base?

Is the ISO Base 200?

It's confusing, but the script tells you what it *should* be, not what it is.

However, camera.h defaults to 200 for DryOS >= 49, so it should be OK.

Another thing to check would be the market to real conversion factors. (SV96_MARKET_OFFSET, ISO_MARKET_TO*, ISO_REAL_TO*)

These can be found by comparing the market and real values after setting ISO in the UI and half pressing. See core/shooting.c for how they are defined and used.

Now PROPCASE_SV and PROPCASE_SV_MARKET are equal to G7X.
Did you verify that the values look like SV96 values?

Don't forget what the H stands for.

FWIW, market and real ISO seems to be equal on the m10.

Could you try to run rawopint on the M10, just a couple of shoot, and post the log file….
