A new year, a new review ... albeit the results of this one aren't too impressive.

Happy new year ?
A 15mmf2.0 should be a joy to use for astrophotography, already Samyang 14mmf2.8 is much praised there, how do think this One will perform there ?
Can you add coma test ??

You won't use this lens for Astrophotography unless you mount it to an A7s maybe. The performance at f/2 is too low for that purpose - coma-related or not.

Good review of a lens which struggles a bit in the corners but remains almost distortion free...........

If distortion is your worry the Laowa is your baby................as I'm not worried about distortion I'll hang on to my Samyang 14 mm F2.8;


(There are several alternative lenses available in this segment albeit none does exactly match the specs of the Laowa 15mm f/2 FE Zero-D)

It is the coma (probably not only that, of course):
