Fuji XF 10-24 defocus/decentered?

Recommended Posts

Dear fellow X shooters,

I'm a seasoned semi-pro photographer coming from Canon, I'm just starting in the Fuji X series with a brand new X-T30 and I'm loving it! For my first lens I bought a used (in apparent good condition) XF 10-24 f/4 OIS, since I also loved that focal range on my former APS-C canon system. At first glance everything was working great at close up shots with that lens, unfortunately after close inspection I started noticing some strange asymmetrical right side, defocused shots when shooting landscapes at focal lengths greater than 10mm. I tested for decentering with a lot of focal length and aperture combinations with the natestech test chart, with both handheld with OIS and on a tripod without OIS and can't in all honesty see decentering effects. A physical inspection of the lens also shows no signs of significant dust, no fungus at all, no rattling, no bent bayonet, no scratched elements, noting.

I do get slight less bluring when manual focusing (with peaking aid) the same scene, versus autofocusing (single point, non-continuous AF).

I'm at lost here. What can it be? Should I return the lens? Could the camera somehow be the culprit here? Should I lent a lens to test that hypothesis?



Best regards,

They have some sample variations on this lens. I needed to buy 3 of them to get one non decentered sample. If you found this good sample it is one of the best and sharpest lenses in the lineup...

One expects flawless lenses in this price range! It would probably be acceptable with third party lenses.

My lens shows refocused areas at 10mm, makes it useless to me!

      Hi, so I shoot mostly using the LCD, from the hip, and I encountered a program today with my XT1's. Somewhat similar to an old post: https://www.fuji-x-forum.com/topic/1948-x-t1-lcd-fails-when-articulated/
      But my situation is a little different. When my LCD is completely flush, in the normal position against the body, it will be totally blacked out/looking like it's off. I've cycled the 'viewmode' and nothing has helped. I did a factory reset and updated the firmware. But I believe I have a body-to-LCD ribbon short.
      If I pull the LCD away it will work, but only in a limited range. From angled slightly upwards to completely flat facing upwards to the sky. If it's totally parallel with the body to facing downs toward the ground, the LCD will black out/turn off. I can still take photos when it's like this though. 
      I'm pretty sure it's a short in the ribbon — if I push the ribbon around very gently, the screen will go on and off. But anyway, I would like to put this problem out there and see if anyone has encountered it before. The camera has seen a lot of use in the last 3 years, but no drops/damage. Luckily the EVF works normally and used XT1s are pretty cheap now. 
      Let me know if you have any suggestions, thanks!

      Hello everybody.
      I am new here. I switched to Fuji from Panasonic and Blackmagic.
      Quite happy, but I have a big issue with the XF 10-24.
      Please see the attached video, the issue starts at 3".
      Any idea?

      I've been using my XH1 for a couple of weeks and have been shooting video. Recently when I shoot in F-Log I cant get the ISO below 800, it will let me choose a higher ISO but when I drop to 800 the ISO turns yellow and wont let me choose a lower setting. Am I being daft or have I clicked an auto setting by mistake I don't know about ? Any help or advise would be great.

      Hi everyone,
      Quite often, under artificial lights, the screen of both the LCD and the EVF of my Fuji XT20 is flickering/flashing quickly, making shooting unpleasant. This video shows the issue: https://www.youtube.com/watch?v=MWk6i_udD34 When I turn the camera OFF, then ON again, there is an intense flickering at the beginning, but all flickering disappears after 1 second (but the issue might occur again a few minutes later). The issue is present in both normal and high performance mode. 1) Does this happens to anyone else? I would also be interested to know if you don't experience this issue.
      2) If it is caused by the reaction of the LCD/EVF to the fluorescent/LED lighting operating at a certain frequency, why is the issue temporary resolved by turning the camera OFF, then ON again?
      Thank you!
