Technical Drawing and Lens Cut
The document includes a technical drawing of the lens and a lens cut diagram illustrating the internal optical elements, including those marked as ASPH. (Aspherical).
MTF Curves
The document presents Modulation Transfer Function (MTF) curves for the Leica Vario-Elmarit-SL 24-70mm f/2.8 ASPH. lens at different focal lengths (24mm, 35mm, 70mm) and aperture stops (f/2.8, f/5.6, f/8).
These curves plot the contrast in percentages for 5, 10, 20, and 40 lines/mm over the height of the format for tangential (dashed line) and sagittal structures (continuous line) using white light.
The MTF curves are provided for maximum aperture, f/5.6, and f/8 for long focus distances (infinity).
Key for MTF curves:
- Sagittal structures: Continuous line
- Tangential structures: Dashed line
