Well yes, except at f/1.4-f/2 close to MFD. I think the short MFD has been offered as a compensation for the longer FL (58 instead of 50) but without any CRC-style precautions. So I won't blame Voigtländer for offering direct 1:4 ratio. Tamron, with its new 45/1.8, completed the exercise by offering very consistent performance across the field, f stops, and focussing distances (and, similar to the Voigt, nearly zero distortion, which is very welcome). In the MF domain, only the latest Zeiss 50/2 seems comparable - Otus is in another price class anyway.
