Is the samyang af 85mm f 1 4 fe ii good in low light?

Yes, on paper it's a strong choice for low light. It's an 85mm with a maximum aperture of f/1.4, which lets in a lot of light, and it's made for full frame sensors. Primes gather far more light than kit zooms, and this is about as fast as they come.

It's an autofocus lens for Sony E mount, but it isn't stabilised, so in dim rooms keep your shutter speed up or use a body with stabilisation. For the most low-light reach, pair it with a full frame body such as the Sony a7 III or Sony a7 IV. The sensor guide explains why full frame helps most in this kind of light.

If you want something lighter, the Samyang AF 85mm f/1.8 P FE is about 270 grams, though it's slower than the f/1.4.
