For ease of use, the Olympus OM-D E-M10 will be my new walkaround camera for photography and video. A bag full of old manual prime lenses is fun but also a bit on the heavy side and having zoom and autofocus just makes life that much more easy :)
The camera is paired with a great Four Thirds all-round lens - the Olympus Zuiko Digital ED 12-60mm f/2.8-4.0 SWD. It needs an adapter to work on a Micro Four Thirds camera but the end result is pretty nice.
It's not very compact with that lens but it does beat a bag full of manual primes...
Video quality can be seen in the above video which was shot handheld with this combo. I'd call it fair quality from a 24Mbps .mov file.
The lens is super sharp for photography. My flickr E-M10 album is here. All are shot in RAW and some are HDR.
