A handheld light meter reads the light itself rather than what your camera sees, so it gives a steady base for aperture and shutter speed in studio, flash and film work. Key choices are incident versus reflected reading, analog versus digital and whether flash metering is included.
The six meters below range from a battery-free analog Sekonic to a radio-ready flash meter and two compact film-camera meters. Specs come from each listing page. We have not used these meters ourselves, and accuracy figures are the makers’ own.

What to Look For
| Feature | Why it matters |

| Incident or reflected | Incident reads light falling on the subject; reflected reads light bouncing off it |
| Flash metering | Needed for studio strobes and speedlights |
| Power source | Battery-free, AAA or rechargeable cells change upkeep |
| Spot angle | A narrow angle reads a small area from a distance |
