Hm, not as bad as I expected, but not really suitable for landscapes as I did expected.
It is reasonably sharp in the center but only there. The lack of definition as even before you reach the edges is bad for landscapes but it leads to pretty attractive bokeh and OoF areas making this lens a reasonable choice for cityscapes or street photography, or even wide portraits. |

Maybe all Sirius lenses are just average....my Sirius 28-200 f4-f5.8 is nothing special.

I also have a Sirius branded version of this lens in Nikon mount and my experience is in line with these results. At 18mm, it is rubbish at f4 and at f8 it is still soft at the edges even on 4/3. It must be dreadful on full frame. I found the edge softness was not equal left and right, so there is presumably quality control issues with the centring of this lens.
I also found the lens is exceptionally poor when focused on distant objects. It is soft everywhere then. But the centre does get acceptably sharp when focused at closer distances. This is either another quality control issue or the design is badly corrected at infinity.

I find this strange because my Centon branded version was much sharper when stopped down a little, perhaps it is sample variation or there are unknown variations that we are unaware of, perhaps Samyang offered more than one level of quality?
Here are my results with the lens:
