Is the zeiss milvus 35mm f 1 4 good in low light?
Yes, on paper it's a strong choice for low light. At f/1.4 it gathers far more light than a kit zoom, and the lenses guide explains why primes are so good in dim rooms. The catch is that it's manual focus only and not stabilised, so you'll be focusing by hand in the dark and relying on a steady hand or a fast shutter.
It's built for full frame, and the sensor guide says full frame is the better choice for low light and events. Good full frame picks from the list that fits this lens include the Canon EOS 5D Mark IV, the Nikon D750 and the Nikon D850. Check the Zeiss Milvus 35mm f/1.4 page for the Canon EF and Nikon F mounts.
