Is the 7artisans af 50mm f 1 8 aps c good in low light?
Yes, on paper it's a good low-light pick. The 7Artisans AF 50mm f/1.8 APS-C has a wide f/1.8 maximum aperture, and that's what matters in dim rooms. As I say in Primes or zooms, a 50mm f/1.8 gathers far more light than any kit zoom, and it's cheap to buy.
Bear in mind that it isn't stabilised, so in very dim light you'll need a fast shutter speed or a tripod to keep sharp. It does have autofocus, which helps in a dim room.
It fits plenty of APS-C bodies, including the Sony a6700, Fujifilm X-T5, and Nikon Z50 II. For a first kit, pair it with a modest body and keep the budget balanced, as the first camera guide suggests.
