An important notice (for pixel peepers)!
I’ve been shooting with the lens for a week and that’s what I found.

1. IS may and does degrade IQ making sharpness across a frame non-uniform. I believe IS in a ultra-wide lens acts like a tilt-shift unit making unfavorable and uncontrolled shift movements at the moment of capturing a shot. OTOH IS on mode is fine for videographers. With disabled IS the lens still captures sharp images as usual.

2. The lens has got a mild field curvature on focal length between 24 and maximizing at 35mm. Hyper focal focusing is not effectively applicable with this lens. Corner objects are sharper if they closer to the camera. Increasing aperture makes close objects more sharper than ones on distance. So keep this in mind and use focusing or focus bracketing techniques. It must be mentioned that it is common for wide and even normal lenses.

N.B. I won’t decrease the lens rating because I think that these aspects are not negative yet rather its peculiarities. Simply keep them in mind and produce great pictures with this great lens.
