Vivid definition

The Summicron-S 100 f/2 ASPH. (80 mm in 35 mm format) offers creative freedom thanks to a vivid and highly selective image sharpness coupled with an exceptionally gentle blur gradient.

A sophisticated multilayer coating ensures true color fidelity and a genuinely nuanced rendition of skin tones. Whatever the aperture, the imaging quality remains unwaveringly high. Impervious to stray light, the Summicron-S even sets new standards in scenarios with critical lighting.

The highlights

Versatile portrait photography of the highest quality

  • Versatile portrait photography at the highest level
  • Excellent imaging performance over the entire range and at all aperture settings 
  • Extremely fast
  • Creative use of sharpness and blurring for the plastic extraction of motif details
  • Best image quality up to the edges due to aspherical optics
  • Weather- and dust-sealed lens

Technical Details

The lens design comprises seven lens elements in five groups, with a double-sided aspherical element minimizing monochromatic aberrations. Three elements with anomalous partial dispersion guarantee finely balanced chromatic correction.

The cemented floating element at the rear enables phenomenal detail contrast at all ranges.As the length of the lens never changes, it is protected against dust and water splashes, with reinforced glasses on the first and last lens elements boosting robustness.

Modulation Transfer Function

The MTF is indicated both at full aperture and at f/5.6 and f/8 at long taking distances (infinity).

Shown is the contrast in percentage for 5, 10, 20 and 40 lp/mm across the height of the 35mm film format, for tangential (dotted line) and sagittal (solid line) structures, in white light. The 5 and 10 lp/mm will give an indication regarding the contrast ratio for large object structures. The 20 and 40 lp/mm records the resolution of finer and finest object structures.

Distortion & vignetting

Distortion is the deviation of the real image height (in the picture) from the ideal image height. The relative distortion is the percentage deviation. The ideal image height results from the object height and the magnification. The image height of 27.04mm is the radial distance between the edge and the middle of the image field for the format 30mm×45mm.

The graph of the effective distortion illustrates the appearance of straight horizontal and vertical lines in the picture.

Vignetting is a continous decrease of the illumination to the edges of the image field. The graph shows the percentage loss of illumination over the image height. 100% means no vignetting.
