Is the sony a7s good in low light?

The Sony a7S is a full frame camera, and full frame is the size that helps most in low light. On the sensor page, I explain that a bigger sensor gives cleaner high ISO images, roughly one stop ahead of APS-C at the same framing and f-number. I don't have hard high-ISO test numbers for the a7S, so I'd judge it on that size advantage rather than a specific score.

The bigger issue is that the a7S has no stabilisation in the body, so you'll want stabilised lenses for slow shutter speeds. Fast lenses also matter more than the body in dim rooms. Good options for the a7S are:

• Sony FE 24mm f/1.4 GM for wide, dark scenes
• Sigma 28-45mm f/1.8 DG DN Art for a fast everyday zoom
• Sony FE 70-200mm f/2.8 GM OSS for stabilised reach indoors

For more on choosing between fast primes and zooms, see the lenses guide.
