Overall is a good device. I use it a 1 year and figured out the subtleties of different modes, it is enough for travel and outdoor activities.
Key points that delight:
Adequately coping with the dimly lit scenes, even in hands and when the flash is off. GPS tracks files in the format NMEA - enough to pull it and throw in Google Earth. Under the water is also good, color and endurance. In my case, it honestly worked to a depth of 18m.
After 18 meters, the keys become sticky (have not returned to its original state after pressing) and at my own risk, I set the desired video mode at a depth of 15m, and then, without touching the buttons reached 22m and photographed everything I wanted. At a depth of 15 meters inscription displayed threatening reds. Second time I do not make up my mind.
Scary to see how deformed and pressed into the plane of the screen.
There is aperture priority mode, but it is useless - the term "depth of field" strikes out. Else, if you zoom in or zoom out you can hear the loud noise in video shooting mode.
Maybe something will change in the firmware update (yet says that version 1.0 is relevant). Or maybe it is an attempt to somehow elevate a small imperfection matrix and it will be improved in the next model). Whatever it was, I look at the pictures of my first Canon A610 (2006), and even deeply unprofessional eye can see something is missing in the picture in Olympus.
