This applies to any of the f/6.8 Grandagon lenses as well, I imagine. As most of the Grandagons that were manufactured,
have this maximum aperture, isn't?
The only true difference then, between a Rodenstock Grandagon and the Rodenstock Grandagon-N, as you mentioned, it is not with regard to light fall-off,
but with regard to better optical performance given by a better resolution, better colors, less distortion, etc.
The rebranded Rodenstock Grandagon-N is a Caltar-II-N. Is that right?
Thank you again, kind regards!
