Impression
Unfortunately, this is a lens that I have used very infrequently.
When mounted on the M9, I felt the weight of the lens tip and most of my memories are of how difficult it was to focus in the M9’s viewfinder.
Since it was before the spread of mirrorless lenses, I wanted to use this focal length with an SLR, and since I had acquired the SUMMILUX 80mm, it became more inactive, and I finally sold it because it had become fodder in a moisture-proof cabinet.
Looking at the lens construction chart, it is a typical Gaussian lens, with the same lens construction as the SUMMILUX 80mm (with different element thickness and other details) and the same year of release, so it is considered to be a sibling lens designed around the same time.
Specification
Medium telephoto lens for LEICA M-type.
Released in 1980, about 15,000 lenses were produced until 2007.
The earlier model shares the hood with the Noctilux 1.0/50, while the later model has a built-in hood.
The mount part is generally screwed on, so a 6-bit code for lens recognition in digital M can be added.
