Fuji X-E2 Firmware 4.0

Submitted by netgeek on

LibRaw used to support Fuji X-E2 raw files. But with the recent camera update to firmware 4.0, the raw file format seems to have changed and LibRaw is not able to read it. Here is the output from simple_dcraw and dcraw_emu. Both were compiled from the latest 0.18 source:

>simple_dcraw.exe Black.RAF
Black.RAF: Unexpected end of file
Cannot unpack Black.RAF: Input/output error

>dcraw_emu.exe -v "Black.RAF"
Processing file Black.RAF
Black.RAF: Unexpected end of file
Cannot unpack Black.RAF: Input/output error

This forum doesn't let me attach a raw file, so here is a link to my test image on Google Drive.

Can this support be added? Thanks.

Thanks!

Any chance that this patch would be released as part of 0.17?

We have a number of users who are reporting this problem right now. Would it be possible to send us a patch sooner or point me in the right direction on how to fix it myself?

Thanks.

Patch is simple:
Change these lines in internal/dcraw_common.cpp/parse_fuji()

      if ((tag = get4()) > 10000) tag = get4();
      width = tag;

to these

      if ((tag = get4()) > 10000) tag = get4();
      if (tag > 10000) tag = get4();
      width = tag;

(In FW 4.0 extra 4 bytes to binary data has added)
