With the ‚classic‘ rangefinder center weighted metering, from M8 to M9 I allways found it tricky in contrasty landscapes/ bright sky for example to get correct exp in A mode. With mich sky in image it would be underexposed forground, with metering on foreground it would be overeposed sky,…
so sometimes it would take me 2-3 or more images to get a well exposed image.
or dial in -0.7 as a standard, be more on the safe side regadrding highlights, but sometimes give away some dr.
Now with the newer models up to M10r you could, as you know, switch to multi field metering, but only in lifeview mode, which would increase the shutter delay for quite a bit.
Now with the M11 we can use the multifield metering and also the highlight metering without longer shutter delay. We pay for this with a little less nice shutter sound, but we gain a-in my experience- more reliable exp metering. For me it is a big step forward for the M11 / M11M.
