Fujifilm 0x102e field (C-AF settings)

[Phil Harvey]

Pre-Shot is a new function for the X-T3 and only applies with shutter type of Electronic Shutter and Continuous High drive mode

This is unfortunate.  I can decode this specially for the X-T3, but it won't be forward-compatible for future models.

Which camera(s) does 'No flash & flash' apply to? It doesn't mean anything to me.

[greybeard]

0x1443, 0x1444 and 0x1445 D Range Priority

They could be named:
0x1443 D Range Priority
0x1444 D Range Priority Fixed
0x1445 D Range Priority Auto

This is a new function with the X-T3

0x1443
  0=> Auto
  1=> Fixed

0x1444 only applies where 0x1443 is Fixed
  1 => Weak
  2 => Strong

0x1445 only applies where 0x1443 is Auto
  1 => Weak
  2 => Strong

(I can't be absolutely certain of 0x1445 because I have no way of knowing for sure which auto setting was chosen - I can send examples if necessary)

Drive Mode 0x1103

This applies to other cameras in addition to the X-T3

Includes both the Drive Mode (Single, Continuous Low and Continuous High) and the Frame Rate

Here is how I decoded it in order to test:

    0x1103 => {
        Name => 'DriveMode',
        Writable => 'int16u',
        ValueConv => q{
           my $hex = sprintf("0x%X", $val);
           my $rt = ($val >> 24) & 0x0ff;
           my $dm = $val & 0x0ff;
           my $out;
           if ($dm == 0) { $out = "Single" };
           if ($dm == 1) { $out = "CL ${rt}-fps" };
           if ($dm == 2) { $out = "CH ${rt}-fps" };
           $out="$hex : $out";
        },
    },

Given your standards you might split this into two different values

The F30 apparently (from 2006).

[Phil Harvey]

0x1443, 0x1444 and 0x1445 D Range Priority

I'll need a sample for these too.  Thanks.

0x102d Focus Mode

This expands on your existing tags 0x1021 FocusMode and 0x1022 AFMode and differentiates between AF-S and AF-C and adds the size of the focus area.

Most of this applies to other cameras but the size of the focus area has been added for the X-T3.

The following three concepts are included:
- Focus Mode (AF-M, AF-S and AF-C)
- AF Mode (Single, Zone or Wide/Tracking)
- AF Area Size (applies to Single or Zone)

Here is how I decoded it for testing:

    0x102d => {
        Name => 'FocusModeX',
        Writable => 'int32u',
        ValueConv => q{
           my $hex = sprintf("0x%X", $val);
           my $fm = $val & 0xf;
           my $tp = ($val >> 8) & 0xf;
           my $ss = ($val >> 12) & 0xf;
           my $zs = ($val >> 16) & 0xf;
           my $out;
           if ($ss == 0) { $ss=""; }
           if ($zs == 0) {
              $zs="";
           } else {
              $zs="${zs}x${zs}";
           }
           my $fmx;
           if ($fm == 0) { $fmx = "AF-M"; }
           if ($fm == 1) { $fmx = "AF-S"; }
           if ($fm == 2) { $fmx = "AF-C"; }
           if ($tp == 0) { $out = "Single Point $ss"; }
           if ($tp == 1) { $out = "Zone $zs"; }
           if ($tp == 2) { $out = "Wide/Tracking"; }
           $out="$hex : $fmx - $out";
        },
    },

0x102b Focus Priority

This applies to other cameras in addition to the X-T3 and has become increasingly more detailed

It allows you to set Release or Focus priority for AF-S and AF-C modes

Here is how I decoded it for testing:

    0x102b => {
        Name => 'FocusPriority',
        Writable => 'int16u',
        ValueConv => q{
           my $hex = sprintf("0x%X", $val);
           my $f1 = $val & 0xf;
           my $f2 = ($val >> 4) & 0xf;
           my $out="";
           if ($f1 == 1) { $out="AFS Release"; }
           if ($f1 == 2) { $out="AFS Focus"; }
           if ($f2 == 1) { $out=$out." - AFC Release"; }
           if ($f2 == 2) { $out=$out." - AFC Focus"; }
           $out="$hex : $out";;
        },
    },

Noise reduction

For all current Fuji cameras your existing Noise reduction tags are confusing

What you currently have as  0x100e HighISONoiseReduction is actually what Fuji refers to as Noise reduction

I have never seen anything other than n/a for 0x100b NoiseReduction

Fuji has added Long Exposure Noise reduction which I am working on decoding (possibly tags 0x1026 and/or 0x102c but results have so far been inconsistent)

Unfortunate, but it will either be confusing for older models, or for newer models, and to maintain backward compatibility I don't like changing previous behaviour.  However, I'm open to suggestions.

- Phil

Edit: I still need a sample for the D Range Priority settings

[greybeard]

Looks good except:

For AF Area Size - if you split the size between single and zone then it should depend on your "AF Mode 2"  which is visible.

AF Area Size Single Point       : 0 is meaningless if the AF Mode is zone (and vice versa).

and for zone it would be more readable as:

AF Area Size Zone               : 3x3

=======================================

Similarly drive speed is really only applicable for CL and CH

[Phil Harvey]

For AF Area Size - if you split the size between single and zone then it should depend on your "AF Mode 2"  which is visible.

Ah.  So you are saying that the AFAreaSizeSinglePoint is always 0 unless AFMode2 is "Single Point"?

I was hoping that both sizes would be valid.  Sort of makes me wonder why they used two different fields.

Similarly drive speed is really only applicable for CL and CH

Right.

I'm not sure what the answer is but all the recent Fuji cameras (I've checked XE series, XH series XT series and GFX series) use the new definition of Noise Reduction

Thanks.  I'll have to think about this.

So far I have this for the new tags you have given me and the samples you sent:
