21 METERING SENSITIVITY AREAS
3. Spot Metering
Spot metering is ideal for subjects which require carefully-aimed, precise measure-
ment. Since the metering area is 3% of the field of view, you can select a small,
exact area from the overall scene. It is especially advantageous for metering inac-
cessible subjects and when shooting with a telephoto lens. Also very effective for
stage and close-up photography. This system is not suitable for AE photography;
for best results, use manual exposure metering.
Since the optical element is located in close proximity to the focal plane, this new
system of metering sensitivity distribution ensures extremely accurate results. The
actual measuring area, which is slightly shaded, can be seen in the center of the
viewfinder with selective-area and spot metering. It is not visible, however, with
center-weighted average metering.
