Same optical layout as the Voigtlander 75/1.5 Nokton with spacing tweaks. Different special glass location and absence of rear aspherical element for the new Ultron.
Spec differences:
CV 75/1.9 Ultron is 60 grams lighter than the CV 75/1.5 Nokton, 9.2mm shorter, 49 vs 58mm filter thread and the Ultron focuses closer at 0.5m (vs 0.7m). Same angle of view for both at 32.6°.
Interesting. The smaller front element and barrel must be the reason for the slight edge swirl I see in the last sample you posted. I don't remember seeing that with the 75 1.5.
The close focus of 0.5m is unexpected but welcome.
