| L | [] | Matrix metering is adapted to a wide range of subjects. It produces natural-looking results. | 
| M | [] | The camera assigns the greatest weight to the center of the frame. It can be used with subjects that dominate the composition, for example. | 
| N | [] | The camera meters a circle 4 mm (0.16 in.) in diameter (approximately 1.5% of frame). Use for example to meter a specific area of the frame when your subject is backlit or features sharply contrasting areas. | 
| t | [] | The camera assigns the greatest weight to highlights. Use this option to reduce loss of detail in highlights, for example when photographing spotlit performers on stage. |
