Leica 50mm f/1.4 Summilux-SL ASPH

Aperture Series: Curved Creek, Using Field Curvature to Advantage

This aperture series from f/1.4 through f/6.3 looks at performance of the Leica 50mm f/1.4 Summilux-SL ASPH with a subject of ideal “shape” with respect to its field curvature , in particular the right side of the frame, which approaches the camera.


All frames shot in Multi-Shot High-Res mode, which reduces the negative effects of distortion correction; see the analysis for the Leica 50/1.4. Workflow is as detailed in Workflow for Multi-Shot High-Res Mode Images in Adobe Camera Raw.
