The ultimate in image contrast
Aberrations caused by extreme differences between shadows and highlights are particularly obvious in images captured at night. Thanks to the outstanding correction of lateral chromatic aberration, the floodlit facade is reproduced with absolute perfection.
The medium format look
Thanks to its exceptional sharpness, the ZEISS Otus exploits the full potentials of contemporary high-resolution sensors and rewards photographers with images characterised by breathtaking rendition of even the finest details.
The aspherical lens design ensures consistent imaging performance throughout the entire focusing range as well as sharpness to the periphery of the image. The asphere's more complex surface profile can reduce or eliminate spherical aberration and also reduce other optical aberrations compared to a simple lens.
Because this lens is an apochromat, chromatic aberrations (axial chromatic aberations) are corrected with elements of special glass with anomalous partial dispersion. The chromatic aberrations are therefore significantly below the defined limits. Bright-dark transitions in the image, and especially highlights, are reproduced almost completely free of color artifacts.
Virtually distortion-free optics
Dramatic perspectives and a view from extraordinary image angles – ZEISS lenses open up new composition possibilities. Distortion would disrupt the composition because straight lines, whose image does not go through the image center, would be reproduced with a curved shape. This annoying effect is accordingly and largely compensated through elaborate optical designs at all focal lengths.
