over the vagaries of light.

Partial metering

Partial metering limits selectivity

to the area within the outer (8mm

dia.) circle in the viewfinder, ap

proximately 5.8% of the viewfinder

screen. It can be used effectively

when there is a strong light contrast

between the main subject and the

rest of the scene, such as for photo

graphs with a particularly light or

particularly dark background.

Choose this system if you want to

meter a selected area of the frame

then stipulate the final exposure

using exposure compensation.

Fine spot metering

The most selective of the metering

patterns, fine spot metering reads

only the light within the smaller

circle (5mm dia.) and thus limits the

input value to 2.3% of the screen

surface, allowing very precise read

ings of the key parts of a photo

graphic composition. Metering is

exceptionally precise because the

spot metering sensor is located on

the BASIS sensor itself.
