9mm vs 12mm - Brightin Star 9mm f5.6 vs Sony 12-24 f4 G - battle of the ultra-wide angle lenses

In this video I'm comparing two fantastic ultra-wide angle lenses: Brightin Star 9mm f5.6 and the Sony 12-24 f4 G. As a landscape and astrophotographer the Sony was my main go to lens and wanted to test myself if the extra 3mm justifies a new lens and if the Brigthin Star lens stands up agains the Sony lens.
The test was full of surprises, feel free to leave your comments what else would you be interested and if you also have the dilemma to go wider all the time!
