Canon EOS 6D review – Metering
Every Canon DSLR since the EOS 7D (reviewed in AP 7 November 2009) uses the same 63-zone Focus Colour Luminance (iFCL) metering system. Evaluative metering uses data collected from the AF system, as well as the colour and the luminance of the scene, to determine a ‘correct’ exposure. As such, the results of evaluative metering are influenced by the active AF points. If spot AF is selected, then the metering largely takes on the behaviour of spot metering. This is by no means a bad thing because the subject is usually metered for correctly, but it can lead to blown-out highlights should the brightness of the subject in the frame be darker than the overall scene, such as land in an overcast landscape. In the three and a bit years since the EOS 7D was launched, we have seen more improvements from the likes of Nikon when it comes to metering – the 91,200-dot metering sensor used in high-end models like the Nikon D800, for instance.
In most situations, however, we struggle to notice the real benefit of more metering zones when it comes to evaluative metering, and the 63-zone iFCL metering system still holds its own today. All in all, the metering is very predictable, which makes it one less thing to worry about when out shooting.
