With the E-PM2 I made the step from the compact (Lumix) for system camera. With the Olympus I reach now more, but getting there was bit of a hassle:
You can do everything with the camera, but you have to find out how. The touch screen is both practical and modern, on the other hand it contradicts my learned camera operator habits. A manual focus must be supported otherwise than by an electronic zoom on the focus area of the display. I want to aim for the object to be focused and able to turn sharply to an edge or a split "lens".
The menu navigation and -systematik do not open up to me always, even after a long time.
And some things nerves in practice, I will not always confirm only already selected program points when I get the camera from standby and will quickly take a photo. If I've already set everything has to be right there at wakeup.
Triggering via touch is also unusual, for. Example, when you have the camera at the ribbon around his neck and pushes the screen towards you ..
I have read myself into the camera and they studied and experimented and now I use the potential of the camera more and more. You can do a lot and delivers high image quality.
