For unforgettable pictures
The Summicron-TL has a focal length of 23 mm – in terms of 35 mm format, this corresponds to 35 mm – the focal length of the legendary Leica lenses for reportage photography. A truly classical focal length that lets you realize the pictures you see in your mind’s eye and exploit the potential of creative expression! Just as legendary is the maximum aperture of f/2, with which you can bring to life the unmistakeable Leica bokeh. And create your own iconic photos.
