In 1963 the Super-Angulon 1:3.4/21mm superseded the 1:4 model. The same optical cell has been used for the M and R versions. It is a complex design with 9 elements, each of which is made from a different glass type. This lens could only be used on the R-body with the mirror out of the way.

Vignetting now is much less with this redesign and at 1:8 the picture area is now even illuminated. Flare is higher at full aperture than with the 1:4 version. Contrast is medium and coarse detail is rendered crisply on axis (image height 9mm) with the outer zones becoming progressively softer.

Stopping down to 1:4 brings a visible improvement and now this lens is better than the predecessor and at 1:5.6 the rendition of very fine detail is quite clear, but with blurred edges. At 1:8 the optimum is reached and very fine detail is now reproduced over most of the image area with soft edges. As is typical of many lenses from this period, the textural details are recorded with a certain softness that gives the impression at bigger enlargements that the plane of focus has been missed.
