Is the olympus om d e m5 mark iii good in low light?

The site doesn't have a low-light test for the OM-D E-M5 Mark III, so I can't give you a measured verdict. What I can say is that its Micro Four Thirds sensor is smaller than full frame. At the same framing and f-number, that's roughly two stops behind, and the sensor guide explains why.

The easiest way to make up that gap is a fast prime. These three are the ones I'd look at first:

• Olympus M.Zuiko 25mm f/1.2 PRO for the most light at a normal-ish view
• Panasonic Leica DG 25mm f/1.4 II if you want something lighter
• OM System M.Zuiko 20mm f/1.4 PRO for a wider frame

Primes or zooms has more on why a fast prime beats a kit zoom in dim light.
