Camera does not record RAW file!


Recommended Posts

Hello Forum!

 

I did a shoot yesterday and a first happened to me in regards to missing files on the SD card.

 

I shoot JPG+RAW and import all RAW files into Lightroom as I like working with the RAW files and pushing them sometimes.  :)

 

Anyhow ... 3 of my images were missing.  I went back to my SD card and 3 of the images I shot did not have the RAW file!!  The JPG was there but the RAW was missing.  Now ... what differed in these 3 images is the camera aperture, ISO and shutter speed.  Because it was bright outside and I wanted longer exposure (and didn't have ND filter with me) I set camera to 1/20 F22 and ISO to "L".  This was the first time I pushed ISO below 200.

 

I'm guessing that by pushing the ISO to 100 (at least I think that is what L gives) the camera does not record RAW file!?

 

Thanks for any wisdom.  :)

Yes it is mentioned in the manual that the pushed ISO values are JPG only, but that is a nice gotcha, cos the camera doesn't warn you about this... Just like silent mode and flash... :-(

 

Since you work in RAW and the fact the sensor is ISO-invariant, you can better over/underexpose the RAW and then pull/push the RAW in post processing.

Also note that ISO-L and H in fact do the same, and that in ISO-L you will lose a stop of headroom in the highlights.

 

Better stay at base ISO for optimum results and use the electronic shutter or ND filter when it is too light.

    • Looking more like the next Fuji camera we see will be an X-T50 but it is still a rumor and no specs have been published.
    • Hey guys, The shutter on/off button switch may be loose on mine. After turning camera on and pressing the shutter/holding close to the area, the camera will turn off and say 'sensor cleaning'. This doesn't happen if I'm shooting via touch screen at all. Everything else is functional. Anyone else experience this before? Would love a much cheaper fix since Fuji Canada just quoted me $700 CAD to fix it, and considering everything else is functional except that part I'm not even sure why MPMB Main Board parts is being replaced😕 I got no explanation from them either.
    • As far as I know the firmware is not country specific. Are you sure that the filename has not been changed ( I am told this can happen with mac os). That's the only thing I can think of.
    • My x-t5 does not exhibit the focusing switch behaviour as you report it, so that is very strange and indicative of a fault. It does not matter whether the flash is attached or not. Once you set the camera for your studio flash, say 1/250th at f5.6, the camera, which is showing you what you will get at that exposure without the flash, will show a black screen unless the ambient light is brighter than what you would typically get indoors. That is why, as Jerry says, you have to set preview exp/wb to off. I have set a button for this.
    • I connected to FRAME.IO a while back and it works fine, but the camera wouldn't connect to the internet all of a sudden today and would get stuck on the reset screen, including initializing and even switching USB Connection mode. Is anyone else experiencing the same thing?
