The new FujiFilm X series cameras with the 40MP sensor (X-T5 or X-H2) are writing to a new series of tags within the MakerNotes area of the EXIF.
Could someone with access to one of these new cameras help with the decoding?
The tags are:
- 0x1449
- 0x144a
- 0x144b
- 0x144c
- 0x144d
Here is an example of an exiftool command which will show the tags:
exiftool -a -G1 -u -Fujifilm:All -sort <image file name>
all the makernotes tags will be displayed including something like the following:
[FujiFilm] Fuji Film 0x1449 : 67174533
[FujiFilm] Fuji Film 0x144a : 474
[FujiFilm] Fuji Film 0x144b : 302
[FujiFilm] Fuji Film 0x144c : 767
[FujiFilm] Fuji Film 0x144d : 1.8
With the 40 sensor, you can do a crop of 1.4 or 2. I can't find in which tag this information is stored.
The 0x104d CropMode tag indicates Unknown(8) while the values can be:
0 = n/a
1 = Full-frame on GFX
2 = Sports Finder Mode
4 = Electronic Shutter 1.25x Crop
DO you have sample images shot with the different crop options?
Yes, how to post them because they are large files
DropBox and WeTransfer (amongst others) allow you to send files for free using a link.
swisstransfer links with 3 dng files with 0, 1.4 and 2 of crop : https://www.swisstransfer.com/d/0221a0ad-96f8-4b2c-94e2-c14f9b855aff
From reading the manual am I right in assuming that DIGITAL TELE-CONV. only applies to JPEG images?
The examples in the link are Photoshop processed RAF files so its a bit tricky to tell for sure but I can't see anywhere that shows the difference between 1.4x and 2x in these files.
What we can say is that tag 0x104d has a new value:
0x104d => { #forum9634
Name => 'CropMode',
Writable => 'int16u',
PrintConv => { # (perhaps this is a bit mask?)
0 => 'n/a',
1 => 'Full-frame on GFX', #IB
2 => 'Sports Finder Mode', # (mechanical shutter)
4 => 'Electronic Shutter 1.25x Crop', # (continuous high)
8 => 'Digital Tele-Conv',
},
},
The two cropped images have values in tags 0x1051,0x1052 and 0x1053 but I can't see how to tell the difference between 1.4x and 2x from these tag values.
As an update there is a good chance that tags 0x1051,0x1052 and 0x1053 provide a way to distinguish between the 1.4x and 2x crop - but they don't make sense (to me) in the samples - would it be possible to post a couple of jpeg or RAF samples (1.4x and 2x) - unprocessed (i.e. not via Photoshop) - and with the AF point not right in the centre of the image?
