I have both. The Samyang has some coma wide open but the Tamron does not. The Tamron is considerable wider than a 24 mm. The 18/2.8 is better on full-frame than their 12/2 was on APS-C.
I like my Sigma 20mm F1.8 EX DG for indoor events. It has more coma but so does the Sony 20G. The Minolta/Sony A-mount 20mm F2.8 has more coma, but can be a decent landscape lens. I have a few SLR ultra wide zooms that are ok. A Sigma 12-24 is very wide.
I ordered a Tamron 17-28/2.8.
