As the button can also be worn on your lapel as a buttonhole badge, it is a stylish addition to both your camera and your clothing. It is available in three timeless designs – a classic Leica logo (in red or chrome), a limited, premium edition with the 100 years logo or showing an M reduced to the essentials.
