This was a very sharp wide angle lens. It had a control ring that enabled the field to be sharp from highly convex to normal to highly concave.It was used particularly for advert photos of things in different planes.Leica used several Minolta lenses rebadged as Leica with stringent quality control.There was also the Minolta varisoft 85mm f/2.8 and the shift CA 35mm f/2.8.I am not sure if any of these three were used by Leica.There are many tilt and shift lenses by many makers also.The Leica Noctivid designers would know all of these optical possibilities.</blockquote>
