Is the laowa argus 25mm f 0 95 cf apo good in low light?

Yes, mostly because of how much light it lets in. At f/0.95 (the page's spec line says f/0.9), this Laowa is very fast, so it gathers far more light than a kit zoom. The trade-offs are that it's manual focus only and not stabilised, so in dim rooms you'll be focusing by hand and holding still.

Your camera matters as much as the lens. A bigger sensor is cleaner at high ISO, and this lens works on both kinds of body:

• Fujifilm X-T5: APS-C, so the lens runs at its native framing.
• Sony a7 IV: full frame, which is cleaner at high ISO, but the lens runs in APS-C crop mode there.

If you're comparing options, the lenses guide explains why a fast prime is such a good low-light tool.
