Problem with auto focus on XF 50-140mm 2.8

Hi guys, new Fuji-freak here!

I bought yesterday X-T3 with the 18-55 lens and XF 50-140mm f2.8, both used.

At first I was really impressed with both of them but soon I figured out that there's something strange with the 50-140 and autofocus. The problem occurs at the maximum 140mm focal lenght. The autofocus can't focus near. It will only work for longer distances (over 4-5 meters) even though the minimum focus distance should be 1 meter. Even a slight zoom out e.g. 138mm will make the autofocus work normally.

All the settings are in "auto", I'm shooting in single shot mode and autofocus on single point. The problem occurs in every possible setup. Here's a video about the problem (I didn't find my stand so I had to use chair) [ignore the cat meowing] https://youtu.be/g8snv-60DBM

Has anyone else had the same problem or should I return the lens?

Hey,

So the YouTube video is no longer available. However, I do have a simular issue with ny 50-140 lens at 140mm. In Manual focus, during video recording, it seems the focus is sort of pulsing at times which can ruin that part of a video. I am not sure what causes the issue but, I have reached out to Fuji in hopes they can help. I will try to remember to update here if/when I hear back!

 

Did you by chance solve you issue @jufoso?

    • Looking more like the next Fuji camera we see will be an X-T50 but it is still a rumor and no specs have been published.
    • Hey guys, The shutter on/off button switch may be loose on mine. After turning camera on and pressing the shutter/holding close to the area, the camera will turn off and say 'sensor cleaning'. This doesn't happen if I'm shooting via touch screen at all. Everything else is functional. Anyone else experience this before? Would love a much cheaper fix since Fuji Canada just quoted me $700 CAD to fix it, and considering everything else is functional except that part I'm not even sure why MPMB Main Board parts is being replaced😕 I got no explanation from them either.
    • As far as I know the firmware is not country specific. Are you sure that the filename has not been changed ( I am told this can happen with mac os). That's the only thing I can think of.
    • My x-t5 does not exhibit the focusing switch behaviour as you report it, so that is very strange and indicative of a fault. It does not matter whether the flash is attached or not. Once you set the camera for your studio flash, say 1/250th at f5.6, the camera, which is showing you what you will get at that exposure without the flash, will show a black screen unless the ambient light is brighter than what you would typically get indoors. That is why, as Jerry says, you have to set preview exp/wb to off. I have set a button for this.
    • I connected to FRAME.IO a while back and it works fine, but the camera wouldn't connect to the internet all of a sudden today and would get stuck on the reset screen, including initializing and even switching USB Connection mode. Is anyone else experiencing the same thing?
