Is the voigtl nder nokton 75mm f 1 5 aspherical good on aps c?

Yes, on APS-C it makes a good tight portrait lens. The focal length converter explains the crop: this 75mm behaves like about 112mm on Sony E or Nikon Z, and about 120mm on Canon RF. That's a telephoto view, and f/1.5 gives roughly the depth of field of f/2.2 to f/2.4, so backgrounds still melt away.

It's manual focus and not stabilised, so it suits people who take their time. For headshots, the portraits guide puts this kind of length in the tight-headshot range. Good pairings include the Sony a6400, the Nikon Z50 II, or the Canon EOS R7.
