Is the voigtl nder apo ultron 90mm f 2 good for portraits?

Yes, on paper it's a good portrait lens. At 90mm on full frame it sits just past the 85mm focal length I suggest for portraits, and the f/2 maximum aperture gives you soft backgrounds and room to shoot in dim light. The catch is that it's manual focus only, so you'll need to take your time getting the eyes sharp. It's also Leica M mount, so you'll need an M body such as the Leica M10 or the Leica M11, both full frame.

If you're new to portraits, I'd still start with an autofocus lens from my first lenses guide. Whatever you choose, window light or open shade will do more for your pictures than the lens will.
