This 3-way series looks at secondary color correction for the Zeiss Milvus 100mm f/2M versus the Nikon 105mm f/2 DC and the Sigma 105mm f/1.4 DG HSM Art.
LOCA and SLOCA are two aspects of the same phenomenon—insufficient optical correction, generally for spherochromaticism (spherical aberration by color).
