Oh yeah but that would be the same regardless of lens used.
Just like a Painting depends on the artist not the brush but part of the artists job is picking the best brush for the work. All that happens before you start creating.
Lovely lense. I bought it a couple of days ago. I hadn't had a good opportunity to shoot stars but the couple test shots were promising. Decent coma @ f2, 1,4 does show a fair amount but it's bearable. This is a lot better imo than for example Nikkor 17-35 or 24 1,4.
A sharp lense and very good construction. Focus ring is good, a lot better than what for example Nikkor af-s 20mm has. Not as good as that of Samyang 14mm.
