Zeiss Milvus Distagon T* 25mm f/1.4

Resolution

Tested on the 45MP Nikon D850, the lens delivers an excellent set of Image Engineering test results. It’s spectacularly sharp in the centre, even at f/1.4, and only gets better on stopping down. The corners register lower values, but examination of real-world images reveals that the lens can still resolve very fine detail, just at low contrast. The optimum apertures to attain best sharpness are f/ 5.6 to f/8.
