Frequently Asked Questions
What camera system is this lens compatible with?
The Summarit-S 70mm is designed exclusively for the Leica S Digital Camera System and is not compatible with other Leica mounts or third-party camera bodies.
What is the equivalent focal length on a 35mm full-frame system?
On the Leica S medium format sensor, 70mm provides a field of view roughly equivalent to a standard 56mm lens on a 35mm full-frame camera, making it a natural everyday focal length.
How close can this lens focus?
The minimum focus distance is 1.6 feet (0.5 meters), allowing you to work relatively close to subjects for a standard focal length lens.
What do the aspherical elements contribute to this lens?
The aspherical surfaces correct optical aberrations such as spherical distortion and coma, resulting in sharper images with higher contrast, particularly toward the edges of the frame.
What is the maximum aperture of this lens?
The maximum aperture is f/2.5, which provides a bright viewfinder image and allows for selective depth-of-field control.
