Attention:
1. This type of light meter measures the brightness of the subject within the measuring range of about 40°, and calculates the exposure based on the 18% reflectance. When metering, please adjust the exposure according to the actual reflectivity of the measured object, that is, white plus black minus.
2. This type of light meter measures the light evenly within the measuring range of about 40°. When metering, you should aim at the subject and pay attention to the brightness distribution of the scene in the metering range. Avoid or at least include the bright sky or the background in the background. Strongly reflective water surface, otherwise the metering indicator will be too high, if not compensated, the subject will be underexposed.
3. Since the light meter and the camera lens are not on the same axis, the metering coverage will shift to the direction of camera's cold/hot shoe when the shooting distance is short.
4. This type of light meter can work normally in the range of 0~40℃. If the temperature is too low, it will affect the display effect of the LCD screen and the battery power.
5. This type of light meter is not waterproof, please not use it in the rain.
