Hi everyone,
I am experiencing a persistent and frustrating issue with my Fujifilm X-T50 and I’m looking for advice to understand if this is a known firmware bug or a mechanical defect requiring service.
When I turn on the camera and take a picture immediately in Manual Mode, the first frame is significantly overexposed. Any subsequent shot taken immediately after is perfectly exposed, even though the settings (ISO, Aperture, Shutter Speed) have not changed.
The issue is intermittent. It stopped happening for a period but has recently started occurring again. Also the problem does not persist when i am using electronic shutter but on this side i'm still conducting some tests trying to switch between ES and MS.
I've checked many times all the settings like PREVIEW EXP./WB IN MANUAL MODE / NATURAL VIEW, i'm sure those setting aren't the causing the issue.
It happens with both:
Fujinon XF 18-55mm (Digitally controlled aperture).
Meike 35mm (Fully manual/analog aperture with no electronic contacts).
Since it happens with the manual Meike lens, I believe we can rule out lens communication issues.
Has anyone else experienced this first shot overexposure on the X-T50 or similar X-Processor 5 bodies (X-T5/X-H2)? Given that it happens with a manual lens, I suspect this might be a mechanical shutter issue or a firmware initialization bug where the sensor gain isn't resetting fast enough at boot.
The two pictures i have attached show the problem at the same settings, the image is simply overexposed no other artifacts or strange colors.
Should I send it in for warranty repair immediately, or is there a known firmware workaround?
Thanks for your help!
