In the built-in become standard,Digital Camera Battery metering table before handheld metering table is very common. There are two main types of metering table (except for flash with metering table); The reflected light table and metering incident light table metering.
Metering table and built-in light canon lp-e5 battery reflected the working principle of metering table similar, just the former cannot be accurately measure the light to lens (because no calculation of the lens to the effect of attachment). But the positive side is, hand-held center-weighted average metering or spot metering table usually can be measured in the scene is difficult to take place, the light Angle range is about 1 °, therefore in the measurement of the part of the special light can be very accurate.
Incident light table is working principle chart is different, it is measured in light on the object illuminate intensity, and not the strength of the reflex the light. Use this list is not the advantages of objects of light absorption or the reflection of the nature, into consideration in the disadvantage is read when must let table and the object from nearly enough.
Built-in metering reflex the light meter to measure the incoming light meter to measure the object exposure metering of light.canon lp-e6 battery
