The color saturation depends on the type of pictures: In lower >light (1/60, f 4, E100s) the colors are very saturated, the shades are >very rich; in bright sun light (above f 4, 1/250 E100s), the lens looses >it's magic and is as fine as the Summitar or Summarit. It is my "one >and only" 50 mm lens for rainy or strongly overcast days (if I look >for color richness), and in b/w up to f 4, 1/250, 200 ASA (if I look >for richness in grey tone rendition).

Compared to the rigid >chrome Summicron, my lens had an increased contrast but a reduced >sharpness.
