Is the voigtl nder nokton 55mm f 1 2 sl iis good for portraits?

Yes, it's a good portrait lens, with one catch. Its 55mm focal length sits between the 50mm and 85mm that the portraits guide recommends, and f/1.2 gives lovely background blur. On full frame it's a natural, slightly tight view. On APS-C it frames like about 82mm, close to the classic portrait length.

The catch is that it's manual focus only. For posed portraits that's manageable, but if your subjects move or you want quick, reliable focus, you'll be happier with autofocus. If you want autofocus, the 85mm f/1.8 in the guide is the classic full-frame choice, and the 50mm f/1.8 is the cheapest great option for people.

You can check which bodies it fits on the lens page.
