The redesign in 1969 by Mandler introduced new glass types and the famous lanthanium crown, that gave the summicron its name and fame, was dropped and replaced by flint glass. The lens shows in the picture an overall high contrast and good central definition of the fine textural detail, becoming rapidly soft in the outer zones.
