Is the tamron sp 85mm f 1 8 di vc usd good in low light?

Yes, I think it's a good choice for low light. The f/1.8 maximum aperture lets in a lot of light, and the stabilisation helps you hold a sharp shot when the light drops, so you can keep shutter speeds down without pushing the ISO too far.

It's made for full frame sensors, which suit dim scenes best, as Sensor sizes explains. If low light is your main worry, pair it with a full frame body such as the Nikon D750 or the Canon EOS 6D Mark II.

It's an 85mm, so it's really a portrait lens. Indoors you may need to step back. For why fast primes matter so much in dim light, see Lenses.
