Cutting out some favorite part of the scenery is one of my hobby for long time since silver salt generation.
Half a century ago, there were world wide famous small camera company named Ernst Leitz GmbH. Their lens design were superb and excellent in comparison with another company's ones. The designs were based on "Kante Theory", cutting sharpness of the overlap portion on the three dimensional images.
The lens design concept of Ernst Leitz GmbH was completely different from another companies.
Now I'm working on Vario-Ermarit lens 45 years later since my good old time with sweet and gem memories.
