Dynamic Range
From our real-world testing and from the score given by DxO labs in its testing, we believe the E-5 to have a maximum dynamic range of 10.5EV. While this is not a bad performance, it is more in line with entry-level models rather than a professional model such as this.
The camera features an i-Enhance mode, which is designed to optimise the exposure by lightening darker areas of the image. However, this can be achieved just as well by processing the raw file, and once the new raw format is more widely supported by the main raw processors there will be even more scope to pull added detail from the images.
