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!

That doesn't look like flickering, that looks like the screen refresh rate changing based on brightness.  Make sure you have the latest firmware installed and it it persists send it in for service.

Actually I'm noticing similar issues on my X-T2 with the newest firmware.

 

I see it both in the EVF and LCD; especially around FL light sources it's really bad.  This looks exactly like seeing the raster line in the older TV screens when shot with a video camera, you'd get that faded line scrolling up and down based on frame-rate and shutter speed.  I'm also seeing noise patterns in low light.

 

I think there's a larger issue going on here.

 

I'm going to submit this as a service request and see what kind of response I get and post results here.

In contacting Fuji support they are unaware of this issue, however my unit does it and so does another copy that a local dealer has.  So apparently this is a hardware bug (maybe a firmware update will fix this?)

 

Here's my video showing it's existence in both EVF and LCD:

I've sent this info to Fuji and they're going to investigate, so if you have an X-T2 with this issue I'd highly suggest you contact Fuji support and fill out a Warranty Repair form (Google it) and send it in.

My X-T2 suffers the same problem. Not only artificial light, also bright daylight, sun, ...

Flickering occurs in "manual exposure preview on", with "off" there is no flickering. :D

Flickering occurs both in AF mode "S" and "M" - most interestingly :unsure: 

Using AF mode "C" flickering disappears :D

EVF Auto brightness yesterday triggered the problem, today issue comes in Auto brightness and also manual brightness... :o

power mode does not affect the issue.

    • I use a TECHART ring to mount Canon EF lenses on the GFX 50S-II and 100S-II, maintaining image stabilization and autofocus. The only limitation are lenses with a small rear element diameter that make it impossible to cover medium format. Fast lenses like the EF 85/1.2L or the 100-400L, however, work great.
    • I also use a Nikon to GFX Fringer and it works very well.  24mm f/1.8 vignettes so best used on 35mm mode.  50mm f/1.8 covers the entire frame very well with no issues and is a superb little lens. 105mm Sigma vignettes slightly but is perfectly usable. 300 f/4 likewise the 105.  I have a 70-200 f/20+.8 incoming to test so will report back but I'm expecting a little vignetting.  Even in 35mm mode the image is still 60MP and if you're prepared to manually crop and correct you can get 80-90 MP images.  I also have a C/Y to GFX adapter.  The 24mm Sigma Superwide vignettes strongly. Ditto 28-80 Zeiss Sonnar. 80-200 f/4 Sonnar is perfectly usable. All work fine as 35mm mode lenses.  I also have an M42 adapter which I tried with the Carl Zeiss Jena 135mm f/3.5 with good results. 
    • Ahh, the infamous brick wall photos… 😀 According to internet lore, if the dng converter does not properly apply the corrections, you can have it apply custom profiles that should work for you. How to do that is waaaaaay outside of this comment’s scope, but there are plenty of sites listed in the search engines that step you through the processes. Best wishes.
    • Jerry Thank you very much. That is extremely helpful. It seems that the camera and the lens have the latest firmware update, so it appears that the corrections should be applied automatically. The lens arrived this afternoon and I took some quick test shots, in which the correct lens information appeared in the EXIF files, so that sounds good. I used Adobe DNG converter to convert the Raw (RAF) files, and then opened the DNG files and saved them in PSD format. However, with a beautiful, clear, cloudless blue sky, there were no lines near the edges to check if distortion had been corrected. Another day I plan to photograph a brick wall. Thank you for your help.
