Samyang 12mm F2 Centering Quality?

I didn't want to start another 'Is my Lens Ok' Thread, but am forced to because I just can't seem to decide if I should return or keep this lens.

I ordered the lens from amazon before leaving for my vacation. When I got it I noticed that there is severe softness on the left side when used wide open at F2. But the softness goes away by f5.6.

So I ordered a replacement. Now that I have a replacement, I noticed that it too is not really perfectly centered. Better than the previous one, but still decentered. And the softness doesn't go away completely when stopped down.

So, my question is should I keep one of these? Which one? Should I return them both & try my luck again in the future Or Is this the level of centering expected from Samyang / Rokinon?

I may be spoiled by my Fujinon 16 55.

Sample from my First Copy:

Here are a few samples where I used the first copy wide open:

I can just catch the Softness / Out of Focus on the left hand side

Should I just get the Fujinon 16mm 1.4 for astrophotography?
