Stabilization worked fune with viltrox lenses for me, maybe samyang hasnt figured their stuff out yet. Have you found any firmware updates to the lens.

Thank you for replying and good to know that IBIS does work with third party lenses, or at least with viltrox.

Unfortunately there seems to be no new firmware for the Samyang AF 12mm 2.0, yet.

However, I'm not sure what Samyang could figure out to fix this. There shouldn't be much more to do then tell the body the focal length of 12mm. Which it does, as the focal length of 12mm shows up in the EXIF.

I hope this problem gets more attention as soon as more people start buying this lens.

If you unscrew the lens, so that the electronic contacts dont touch, and set the focal length manually to 12mm, does the stabilization still not work? Just asking, because then the lens should be equal to dumb mf lens, and stabe should work no matter what

Interesting!

I've just tested this with a shutter speed of 1/2s and 3 images each.

With the lens fully mounted, 1 came out okayish and 2 blurry.

With the lens unscrewed, all 3 were perfectly sharp.

The respective images both show a focal length of 12mm, the first ones via electronic information of the lens, the last ones via manual setting.

I guess I have to contact Fuji support. I hope they care for a bug like this, even though it's linked to a third party lens.
