Best camera for the voigtl nder apo ultron 90mm f 2?
The Voigtländer APO-Ultron 90mm f/2 is a full-frame manual-focus lens for Leica M mounts, so every body it fits is a Leica M. My pick is the Leica M11. It's the newest body on the list, and it's the one I'd buy if I were starting from scratch.
If you want to spend less, the Leica M10 or the Leica M (Typ 240) will still give you full-frame results with this lens. The Monochrom bodies are worth a look only if you shoot black and white exclusively.
At 90mm on full frame, this lens works well for portraits, where a longer view keeps faces in proportion. Check the full lens page for the complete list of compatible cameras.
