X-T50 stops down to autofocus

For some reason, possibly operator error, my X-T50 stops the lens down to autofocus. Happens with three lenses, OEM and third-party, all bought new (haven't tried any others). If I set the aperture to (say) f16, when I press the back button to AF, the viewfinder gets very dark, and the camera misses focus. I can watch it hunting, and it occasionally finds focus and then loses it. This appears to have happened today, even at f5.6. Has anyone else had this happen? Are there settings I am missing? (There always seem to be. 🙂)

in AF-C FujiFilm cameras stop down when you half press the shutter - in AF-S they don't

I thought it might be something like that. I think something else MAY be going on as well. Am going to experiment.

I found out how to defeat that, now to see if I get better results.

 I have just read this. All the XT cameras I have owned stop down with a half press of the shutter regardless of whether AF-C or AF-S is selected. This includes my X-T5, which I have just tried with all three shutter types. I haven't experienced your problem. What happens when the button is fully depressed is another matter. I don't have enough knowledge of that. I don't own an X-T50, so I can't say if it is the same.

      Spots on my every images

      If the spots are in the same place every time then its likely a dirty sensor - you can buy a sensor cleaning kit and do it yourself or take it in to get cleaned professionally.

      X-T50 Bug: First Shot Overexposed after Startup

      By JacopoAlfonzo · Posted

      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!

      Hi everyone, I’m hoping you can help me with an issue I’m having with my images. Every photo I take with my Fujifilm X-T2 has visible spots on it (as shown in the attached photo). Because of this, I have to spot-heal all my images in Lightroom just to remove the spots, which is very time-consuming. I’d really appreciate any advice or suggestions on what might be causing this and how I can fix it permanently. Thank you so much for your help!

      Non zero shutter count on new camera

      By abmet · Posted

      Like jerryy said lithium batteries are shipped partially charged. Do you have ibis turned on, and is it set to continuous or shooting only?  If continuous that could be the noise you hear.   I’d also contact Amazon on the shutter count and missing wall plug.
