It doesn't matter whether you own one of the best mirrorless cameras on the market right now. The best light meters will provide more accurate and consistent results than your camera's built-in light meter. And the Sekonic Studio Deluxe III light meter stands out for having a passive solar cell, which means you’ll never have to worry about changing batteries.
So why are light meters so accurate? Well, most cameras only take readings from light that is reflected off the subject. Several variables can impact this reading including the subject’s reflectiveness and the focal length being used. Camera meters are also designed to provide an ‘average’ exposure to prevent clipping, so they will quell bright highlights and lift dark shadows in an attempt to realize tones as middle gray.
