Hello all. I'm very new to the :43: system. My fiancee and I got each other the GF1 w/ 20mm for Christmas so I've only had a few weeks to play with it. My current shooting style is to first spot meter in Aperture mode and then move to Manual and do most of my shooting there, making adjustments to both aperture and shutter speed as necessary. I've noticed that in Manual mode, the exposure compensation graph updates (+/- EV) as the camera is moved around. Is this just a suggestion based on the camera's meter? I don't think the camera is actually applying that setting on it's own because as far as I've noticed, I don't think any of my shots have EV comp when I bring them up in Lightroom. I'm also curious as to how setting the ISO sensitivity to 1/3 EV actually works. Is there truly 640 ISO or does the camera just split the difference between 400 and 800?
