Technically by cons, this compact really opens up new possibilities: a large aperture at all focal lengths, adjustable to correct the exposure directly without going through the menus, the "experts" whose settings can no longer happen when is accustomed to working with an SLR (like the auto ISO range adjustable for example), recording in RAW and so on.
An ideal compact housing as the second, when we can not or that we do not want to load up with its main reflex camera.
