I've now come to the conclusion, by testing multiple EF-M and EF lenses in various scenarios, that my M5 does, indeed, underexpose a bit but nothing much different than what my 5DMKIV does (...about 1/6 to 1/3 of a stop...).

Where it is very different is in having an Evaluative Metering logic that seems to be a completely different one from that on the previous DSLRs and Ms I used.

Any noticeable portion of white or highly reflective surfaces in the shot (...as low as 5 to 10% of the whole scene...) will immediately trigger an inordinate amount of "exposure defensive bias" by consistently underexposing 0.5 to 1.0 EV, in TV and Av.

Since this is a consist behavior that I've now learned to "read" and since I can have the histogram displayed for all shots in both the viewfinder and the back LCD, I've decided to adapt to it.

As for the 18-150, I still want to test a another copy side-by-side to see if the performance on this one is the most it can give.

Thank you guys for all your help! Much appreciated

PK
