It’s compact, durable, and offers a straightforward interface that doesn’t overwhelm you with unnecessary features.

Key Features to Consider

Before I settled on my Sekonic L-358, I focused on these critical features:

  • Light Measurement Modes: The L-358 offers incident, reflected, and flash measurement modes. I found incident metering particularly helpful as it measures the light falling on the subject, giving me more accurate exposure readings.

I compared the L-358 to other Sekonic meters like the L-308X and L-858D. The L-358 struck a perfect balance between features and affordability. While newer models have more advanced digital interfaces and Bluetooth connectivity, I found the L-358’s simplicity and reliability perfect for my workflow.

Tips for Using the Sekonic L-358 Light Meter

  • Always calibrate your meter before critical shoots to ensure accuracy.
  • Use the incident meter dome for measuring the light falling on your subject, especially in mixed lighting conditions.
  • When measuring flash, trigger the flash manually or use the meter’s sync cord for precise timing.
  • Keep the meter clean and store it in a protective case to maintain its accuracy and longevity.
