The concern I have from reading reviews is it's exposure control interface. Is it possible to manually control shutter, aperture, and ISO in any kind of useful way? I just spent some time with the on-line PDF manuals and am still scratching my head.
Firstly the manual is rubbish, disgraceful and Sony should be embarrassed about the dreadful state of documentation for these cameras.
I've only had my RX100 a couple of weeks so it's still not something I'm completely comfortable with yet.
The only real way to understand them is to use them and work through the menu options until you find a combination of settings that make sense to you for your own style of shooting.
I've now found a combination of setting I
find useful and I can set the major functions(speed/aperture/ISO) relatively
easily and quickly without too many button presses. Manoli's settings are different to mine, yours will likely be different again.
I nearly gave it up as a disaster, the ergonomics are so terrible because there's so much functionality to pack into too few controls really.
However once you start shooting with it you'll discover why it's creating such a stir, the picture quality is really quite astonishing.
