Just got the new M10 two days ago and trying to understand the differences between it and the M240.
I often used the spot metering on the M240 for street portraits by creating a separate user profile. I set the Light Metering Mode to "Advanced" and the Exposure Metering to "Spot." I saved the resulting set up as a user profile. I was able to go to spot metering without physically turning on the Monitor by selecting the Spot User Profile.
The M10 seems to require a different solution to quickly go to Spot as there is no "Advanced" metering mode. On the M10, I set the Exposure Metering to "Spot." When I want Spot metering I turn on Live View. When Live View is off I assume the metering goes back to center weighted. Has anyone found a faster solution?
