This is an issue that I need to understand because the price of the repair is almost the price of the Xpro-2.
So I'll repair it myself.
The issue result : Black pictures with no visual information in post prod (exposure max with raw files etc.)
When this happens ? : in conditions of high luminosity with mechanical shutter
What are the settings when this happens ? :
-Exposure mesure modes- Every ones (spot, multi etc.)
-Exposure compensation- Every ones (+-0, +1, -1 etc.)
-Aperture modes- wide apertures but sometimes at small apertures (even with High ISO or ISO auto)
-Shutter type- mechanical only (and of course M+E when it switch automaticaly to M mode)
-Shutter speed- high values from 1/8000 to 1/1000 but sometimes even 1/500 (in some situations it works till 1/1000 and it works in every situation for 1/250 and slower) the A mode sets directly high values in high luminosity.
-ISO mode- Every mode and value (even H or L)
5. What did I do to verify if I can fix it ? : reset, format SD cards, update firmware, sensor cleaning, defibillation etc.
6. My question is : is it a shutter issue AND why this works sometimes at 1/500 and even sometimes at 1/1000? . Maybe the shutter is ok but the transmission is not ok between the sensor, the motherboard and the shutter. So the problem may be the sensor or the motherboard. The sychronisation between the sensor and the shutter may be not the same.
Indication : the sound speed of the shutter is the same at 1/125 and faster.
I've read every post talking about shutter and expostition issues and decided to ask about this special problem.
So I hope that someone can help me
And help others in the same case.
Before I'm taking my XT3 for repair, making one last check:
My ISO dial apparently stopped working - the ISO level is on 320 and turning the dial just won't do anything anymore.
Also, tried to set the command dial to change the ISO with no luck, and I'm pretty sure I've adjusted everything correctly in the menu.
The only time the ISO DO change is when I put the camera in F-LOG, then it changes to 640.
Any ideas? I'm pretty lost here.
Hello everyone, pardon me if this is a newbie question but in my fuji X-T3, the minimum ISO for movie/video mode is 1000 and it seems that I can't turn it lower than that. Does the camera detect the ambient lighting and keep the value to 1000 or is it because of the lens that I'm using? (which is fuji xf 18-55mm f2.8-4 by the way) or maybe there is a way that I can change that in my settings? Thank you in advance for your feedback.
I tried to adjust the command rear dial for ISO, but was not successful.
I went through the correct procedure: Wrench, Button dial settings: command dial settings: back dial setting: ISO.
I was able to change it for exposure compensation but not not for ISO.
Any help would be appreciated.
As far as I know you can’t change this behaviour with an update. Use an editing software to combine the files. Perhaps you can merge them on your computer using a shell command, too (works sometimes, depending on the operating system and the underlying disc‘s format).
Rico Pfirstinger wrote some books on Fuji X-cameras incl. a few pages on DR. It's in all of his X-pert Tips books. Furthermore, cambridgeincolour.com has extensive explanation pages on all sorts of photographic topics. Just search on their site for dynamic range. The key is that you cannot correct blown-out highlights but it is easy to correct deep shadows in post processing. Cameras have two ways of addressing this: either an HDR-feature or an extended DR feature.
