I feel like I’ve wasted my time with the native lens offerings* of the Nikon Z7 and Canon EOS R to produce technically mediocre images.
Accordingly, I’m now exploring more about the performance of Zeiss Milvus and Zeiss Otus lenses on the Nikon Z7 (using the Nikon FTZ lens adapter).
But only on the Nikon Z7—the Canon EOS R is on the back burner, because the Canon RF 24-105mm f/4L IS bores me to tears and is now well documented, and there are no other native lenses available to me yet—but see Waterfall Amid Aspen (Canon EOS R) which gives a solid idea of the potential of Zeiss DSLR lenses on it.
