Hello everyone,

I just registered here because I also encountered this issue.

I also bought the new Samyang 12mm 2.0 AF and I also borrowed MF version for comparison needs and I though AF version was superior until I found this thread. I just tested both lenses on X-S10 with a shutter speed of 1/2s. I tried to take shoots with the same physical settings. Here are the sample shots, cropped 100% from the central part of images:

Shutter speed 1/2s, handhled

Left - AF version, middle - AF version rotated to disconnect pins, right - MF version

I can confirm that apparently IBIS is not properly working on AF version, while it works really nice on MF version. Also, AF version rotated to disconnect pins also works much better than connected AF lens.

Thank you very much for confirming that it's not just one bad copy, but apparently a bigger problem.

Yesterday, I've contacted Samyang and already received a reply:

Dear Customer

Hello.

Thank you for your inquiry mail.

We are going to check about your issue and if there is problem, We will solve this problem through the firmware update.

But, It needs time for confiming the issue and improvement the software.

Therefore, We will notify through the our web-page when we complete the develop new firmware soon.

If you need any other things, Please let us know.

Thank you very much!

Best Regards

I hope, they can confirm that it's an issue solveable via firmware update.

Now you can tell them that a second Owner of the AF Samyang has the same problem like you. A second owner reporting exactly the same problem as yours makes pretty sure that Samyang has just delivered buggy firmware.
Cheers

I have one coming up in the next days, and i have the manual one, so I'll be able to give an additional data point... Shame if true, was really excited
