The Rokinon 85mm f1.4 AF FE is a very good lens overall, but you may still want to stick with Sony’s options.
When testing the Rokinon 85mm f1.4 AF FE, I admittedly ran into problems with the autofocus performance that needed to be fixed. Luckily, I knew how to do it with a quick clean of the communication contacts. But the fact that I needed to have this knowledge is something that I’m not sure the average photographer has–at least those who would be attracted to the more affordable Rokinon 85mm f1.4 AF FE option. If you get beyond this, you start to realize it’s a fantastic lens for portraiture. On the Sony a7r III, it’s capable of focusing very accurately, albeit still slower than Sony’s options. But I’m positive in saying that if one looked at the images side-by-side from each lens without pixel peeping, no one would be able to tell the differences between them.
