Is the panasonic leica dg 25 50mm f 1 7 good in low light?

Yes, for a zoom it does well in low light. Its f/1.7 maximum aperture is wide for a zoom, so it gathers far more light than a typical kit zoom. It isn't stabilised, though, so in dim rooms you'll want a steady hand, a tripod, or a higher ISO. On Micro Four Thirds, f/1.7 gives about the depth of field of f/3.4, so backgrounds blur less than they would with a faster full-frame lens.

If low light is your main subject, a fast prime still gives more light for the money. See Primes or zooms. Sensor size also plays a part, and Sensor sizes explains when full frame is worth the extra cost. This lens fits many bodies, including the OM System OM-1, which is a good pairing for dim scenes.
