Nikon F6 Center-Weighted Metering, Spot Metering, Filters that require filter factor

“: Center-Weighted Metering

•Center-Weighted Metering places special emphasis on brightness within the 12mm-diameter circle in the viewfinder, so it is useful for basing exposure on a specific area of the scene.

CSM b4: The area of the Center-Weighted meter’s sensitivity can be changed to 8mm-dia., 12mm-dia., 15mm-dia., 20mm-dia. circle or average of the entire viewfinder (x 98).

ˇ: Spot Metering

•Nearly 100% of the meter’s sensitivity is concentrated on the 4mm-dia. area (approx. 1.5% of entire frame) within the selected focus area of the viewfinder. Use Spot Metering to base the exposure on a very small area within the frame, such as with backlit subjects or high-contrast scenes.

•When Spot Metering is selected, shifting the focus area also shifts Spot Metering to the appropriate position. In Group Dynamic AF Mode (x 52), center focus area within the group is activated. However, Spot Metering area stays at the center (does not shift) as long as Dynamic AF Mode with Closest Subject Priority (x 53) is activated, when a non-CPU lens (x 39) is used or “Other screen” is selected in Custom setting “b6: Screen comp.” (x 98) (meter’s sensitivity area becomes 6mm- dia. [approx. 3.3% of entire frame]).

Filters that require filter factor

Effect of Matrix Metering may not be fully attained when a filter that requires filter factor (x 169) is attached. In this case, Center-Weighted Metering is recommended.

CSM f3: Function of the FUNC button can be set to “Matrix metering”, “Center-weighted” or “Spot metering”. When the FUNC button is pressed, metering system can be temporarily switched to one designated (x 108).
