Excellent camera costing less than many pro cameras and performs magnificently.
Olympus have made this a world class product and as a professional photographer I would never need a better product. Some will argue that a pro needs a full frame camera and I say rubbish. I seldom ever enlarge a print larger than 30 X 40 so why would you need anything more. Also with stacking you can have a massive file if you think that that is necessary. It also has a built in tele converter which appears to work quite well and so many other features. I have an OMD EM Mk ii and also an OMD EM Mk III and both are magnificent cameras. I have many Olympus lenses and all perform to professional standards.
