Hello everyone, Recently, I've come across the very detailed videos from Edvard (@edvard2942 on YouTube) about Fujifilm autofocus performance. His tests highlight what he sees as a regression in AF fluidity and reliability starting from certain firmware updates, and that the best results aren't always with the latest versions. I'd love to start a discussion here to compile, based on your experiences and Edvard's tests, a kind of “best firmware list”for each body in terms of autofocus smoothness and reliability (especially in photo and video AF-C with older lenses). Here's a summary of what's already well-established from Edvard's analyses (feel free to correct or add details): • X-T3 Firmwares 3.00 / 3.30 are considered the best – smoothest AF, most natural transitions, fastest and most frequent lens motor adjustments. From firmware 4.00 onward (the one that aligned it with the X-T4), there's a clear loss of fluidity in micro-adjustments and quick distance changes. • X-T4 The AF from the initial firmware (~1.00) already uses the algorithm introduced on the X-T3 with 4.00. It's less smooth than the X-T3 on 3.xx, but generally stable. Later updates did not restore the older X-T3 smoothness. • X-H2S Very early firmware (around 1.03) is significantly better than later ones (3.xx, 5.xx, 6.xx, 7.xx), which degraded fluidity. However, even this best version remains below the X-T3 on 3.xx in terms of pure AF smoothness. I'd really like us to expand this list with other bodies (X-H2, X-T5, X-H1, X-Pro3, etc.). Which firmware gives the best AF according to you, or according to the Edvard videos you've seen? One specific question that's bugging me: Can we expect early X-T4 bodies (with factory/original firmware) to be as smooth as the X-T3 on firmware 3.xx? Or is the difference already there from launch? Thanks in advance for your feedback, any downgrade experiences, and tests with different firmwares and lenses. This could help a lot of people optimize their setup. -

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. -

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!Welcome, dear visitor! As registered member you'd see an image here…

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!Welcome, dear visitor!
