Leica 24-90mm f/2.8-4 Vario-Elmarit-SL ASPH OIS

MTF for Leica 24-90mm f/2.8-4 Vario-Elmarit-SL ASPH

MTF can be measured from a real lens, or computed from a lens design. Leica uses computed MTF which therefore means the graphs are fantasy graphs assuming perfect (impossible) actual lenses. Long experience with a lot of Leica M glass shows that real lenses rarely if ever are fully symmetric across the field, nor do they perform as well as computed charts suggest.

This page looks at MTF for the Leica 24-90mm f/2.8-4 Vario-Elmarit-SL ASPH OIS.

MTF chart

The MTF charts show that the Leica 24-90mm f/2.8-4 Vario-Elmarit-SL ASPH offers outstanding performance at every zoom setting for the central 3/4 or so of the frame, rolling off into the edges and corners. But that does not account for distortion correction, and the MTF is not measured from a real lens.
