Is the laowa argus 35mm f 0 95 ff good in low light?
Yes, this lens is one of the stronger low-light options I list. Its very fast maximum aperture gathers far more light than any kit zoom, and on full frame that's where it does its best work. Two things to know first: it's manual focus only, and it isn't stabilised, so you'll need to focus carefully and keep your shutter speed up in dim rooms.
For a full frame body to pair it with, I'd look at these:
If low light is the main reason you're buying, the sensor sizes guide explains when full frame is worth the extra size and cost. The primes or zooms section covers why fast primes gather so much more light than zooms.
