xilvar: Hm. I wonder if it's possible to eliminate the shutter speed lock button somehow. I shoot in manual mode all the time, and I don't like the idea of having hold down a silly button every time I want to adjust.
Was this really such a huge problem on the x100? I've had plenty of previous cameras myself where I never accidentally changed a top dial... Canon at1, f1, etc.
It only locks on Auto (A).
