Is the ttartisan tilt 50mm f 1 4 good in low light?
Yes, the f/1.4 aperture is the main reason. It gathers far more light than a kit zoom, which matters most when the light is dim. Primes like this are a big part of why primes or zooms is worth understanding before you buy.
Two things to keep in mind. It's manual focus only, so low light makes focusing harder, and it's a full frame lens, so it works best on a full frame body. For low light, full frame is the sensible choice. Good options from this lens's list include the Sony a7S III, which is built for dim conditions, the Sony a7 III, the Nikon Z6 II, and the Canon EOS R6 Mark II.
