Reader Comment: Fujifilm X-T1 Missing Raw Files

Chester writes:

Just curious if you've experienced this yourself or know of others who have. I don't know if this is equipment specific or more pervasive.

I'm using a Fujifilm X-T1 (latest firmware) with Lexar 128GB 600x SDXC memory cards. note attachment.

File directory shows that while shooting the same subject, either the camera or the memory card suddenly chose not to write out the RAW files. then a few minutes later, it resumed writing RAW + JPEG.

I've made no changes to settings midstream. the problem is sporadic and without consistency on what might trigger this. Any ideas on what might cause this? Would burst mode shooting cause this where register just couldn't keep up with the buffer? if so, is that a camera or card issue?

DIGLLOYD: Page 69 of the Fujifilm X-T1 manual discusses programming a button to switch between Raw and JPEG:

To toggle RAW image quality on or off for a single shot, assign RAW to a function button (P 79). If a JPEG option is currently selected for image quality, pressing the button temporarily selects the equivalent JPEG+RAW option.

If a JPEG+RAW option is currently selected, pressing the button temporarily selects the equivalent JPEG option, while if RAW is selected, pressing the button temporarily selects FINE. Taking a picture or pressing the button again restores the previous setting.

That might be the culprit: such a button being pressed without noticing. For a consecutive run of JPEG-only files, it would have to mean the button was pressed a number of times, which is possible if one tends to hold holding the camera in a way that would press it.

Barring the button theory, it seems an unusual bug of some kind. So the first step is to make sure that a function button is not assigned to Raw/JPEG switching. Consider also testing the camera card. Finally, put the camera on a tripod and shoot some bursts where one can be sure of not touching anything but the shutter release.

Chester follows up:

None of my function buttons were programmed for image quality but I think I solved the problem.

I was mistaken when I said I did not change the settings. I went from native ISO of 200 to "L" because I was trying to drag the shutter beyond f/22 to introduce motion into my image by lowering the sensor sensitivity. according to the manual, fuji doesn't record RAW in "L". I don't understand why they would design it this way. anyway, thanks for your help.

DIGLLOYD: I’m not aware of any other brand that jumps from RAW to JPEG by choosing a sub-base-ISO setting. The solution here is an ND filter. A 3-stop filter is generally most useful all-around.
