White Balance and Tint for Zeiss Otus 100mm f/1.4 APO-Sonnar in Adobe Camera Raw — Differs for f/1.4

Get Zeiss Otus at B&H Photo.

With modern digital cameras, a substantial tint difference is often seen at f/1.4 with many lenses; see for example how the Sigma 105mm f/1.4 DG HSM Art behaves. This behavior can vary by sensor/camera but the Nikon D850 is prone to it, and presumably the Nikon Z7 also.

Like the Sigma 105mm f/1.4 DG HSM Art, the Zeiss Otus 100mm f/1.4 APO-Sonnar also shows a significant tint difference at f/1.4 versus other apertures. It is readily visible in any aperture series if not compensated for.

This page uses a SpyderCHECKER ® color checker card to evaluate the difference in white balance and tint between f/1.4 and other apertures, using Photoshop Adobe Camera Raw. In diglloyd Zeiss DSLR Lenses:
