Viltrox EF-FX1 OIS not properly working

[Papiskokuji]

Hello everyone !

I just received my EF-FX1 Viltrox adapter and updated it to the latest firmware. Unfortunately, the image stabilization seems to work only a few seconds after you change the aperture value or you half press the shutter button (much like an IS would work in photography). I can't get to be activated constantly. Do some of you guys have the adapter ? Is there a trick or a known firmware version that works ? Currently, the IS is unusable for video work. I won't keep the adapter if I can't fix this problem. Is the Fringer better in that respect ?

Thank you !

EDIT : I have a Fuji X-T3

The Fringer is much better overall, but you don't get the speedbooster aspect of course. Can't comment on if there is a fix for the issue you are having though.

Thanks for the reply. Actually, the EF-FX1 is a simple adapter, not the speedbooster one. I contacted Viltrox, they just told me to update the firmware. Basically I tried every firmware. The only one kind of working is the latest one. In the Fuji X-T3 menu, stabilization setting is greyed out (you can normally chose if IS is always on or just when you take the picture).

So, so far, IS isn't supported by the Viltrox EF-FX1 adapter. Good to know... Do you get the stablization working with the fringer ?
