Question about Samyang 12mm f/2 NCS CS - Sony E

Very simple, good and precise, Excellent astrophotos!

cameron has actually already said everything about it... have had this lens for over 3 years, great lens, from f4 super sharp to the corner, at f2 and f2.8 in the middle top towards the edge a bit soft, but if you take a picture with a 24MP camera and look at it on a 4K monitor, then you can hardly notice even that...
ultra wide angles have the advantage that the hyperfocal distance is very small, i.e. focusing is rarely necessary, find out where infinity is sharp (for me just after the infinity mark), set the aperture somewhere between f5.6 and f11, and you have everything that is more than 1-2m in front of the lens sharp... never again misfocus, yay!
