Is the 7artisans 60mm f 2 8 2x ultra macro good for portraits?
Not really, not as a first pick. The 7Artisans 60mm f/2.8 2X Ultra Macro is a macro lens, and it's manual focus only with no stabilisation. On full frame it frames as a plain 60mm, a little tighter than a standard 50mm. That works for a tight, deliberate portrait if you don't mind focusing by hand, but it isn't the flattering length most portrait work calls for. The focal length guide puts that sweet spot at 85-135mm.
For portraits, the lens matters far more than the camera, so start with the portraits guide and look for an 85mm. If you like the idea of a 60mm 2:1 macro that also focuses to infinity, the Laowa 60mm f/2.8 2X Ultra-Macro is the same kind of lens for full frame, and it's more general-purpose.
