X100V Flickering

Hey guys. My X100V's screen flickers when I half press the shutter button to focus. This happens at f2.8, less so at f2.5 and f2.2. It stops at f2. It happens a tiny bit at f3.2 but not at f4 and smaller. It's really kind of annoying me. Other than this it's fantastic but if this is a defect I'm returning it...

Normal - keep it

Thanks. I'm just trying to see what people who own it say. One guy told me it's faulty. My ocd is kicking in is all haha

I tried to replicate your experience and cannot.

Tried F/2.8 with Boost Mode = ON and OFF.

No flickering.

Exactly how is your camera setup so I can try to replicate exactly.

Thanks for going through the effort I just tried it again at 1/30, f2.8. ISO 640.

I'll add to my findings:

1) It only occurs if the camera has to autofocus a bit. If i'm focusing on objects with only a few cm of distance difference from the camera it doesn't do it.

2) It seems to happen more often in poorly lit conditions. So if you do the test again it might be a good idea to try that. In my poorly lit room you would have to shoot at ISO 3200 to get good enough light for 1/80, f3.2 for example.

I suspect this happens when the camera is struggling to autofocus ie in a darker lit room. I also notice, looking at the barrel as it focuses, the change in flickering might be due to a sudden drop in exposure when the aperture quickly closes to focus and then reopens. This however does not explain why the flickering stops when I pass F3.2 and is therefore not a definite.

FYI, regardless of your aperture setting, your camera will focus wide open.

Exactly. That's why my original hypothesis was that the camera was losing a stop of light in order to focus hence the sudden darkening of the screen however this doesn't happen past f3.2 so that can't really be the case, can it?

Does it happen with all metering modes?

Just tried. Metering mode doesn't affect anything. Also, I'm in a computer lab right now which is brighter. It's not happening when I focus on well lit surfaces however, when I focus on my black keyboard, black chair or anything dark it flickers. Very strange!

I think it's happening when I focus on anything darker. Maybe because the AF has to work harder.

For me, it did not happend in a poorly lit room. I did have Auto-ISO with a 12,800 max at F/2.8. I suspect there is some setting that is causing it.

Been trying a lot of settings. I'm beginning to definitely think it's a faulty camera :/ I've contacted Fuji support but they're not responding. My return time is running out so I think i've got to send it back...
