Is the nikon z dx mc 35mm f 1 7 good in low light?
Yes, for its class. The Nikon Z DX MC 35mm f/1.7 is a fast standard prime for APS-C, and f/1.7 gathers far more light than a typical kit zoom, which is what low light needs. The first lenses guide puts a 33-35mm f/1.4 to f/1.8 on APS-C in the same role: low light, people, food. The lens isn't stabilised, so keep your shutter speed up in dim rooms.
It fits APS-C bodies natively, such as the Nikon Z50 II and Nikon Z50. On full-frame bodies it works in APS-C crop mode. If you shoot full frame and want the most light, the Nikon Z 35mm f/1.2 S is the very fast option. For a wider view of when full frame earns its cost, see is full frame worth it?.
