I am still sporting and enjoying the OMD EM5's I have had for roughly 5 years.
They still surprise me sometimes to.
My last generation of Canon used the 18mp sensor that I felt lost highlights very easily, creating a solarising effect. The Olympus sensor was (is) a revelation, allowing me to recover some images that my Canon honed perceptions would normally write off. Earlier Canon's and full frames did not suffer so badly, but the 15/18mp sensors made me very over exposure shy.
First image of the day without checking my settings (f2 at ISO 800!)
This has only been recovered with Lightroom's exposure slider (the pole is out of focus, not smeared by over exposure).
After a "quick minute" of processing (some added brightness, and colour)
