Resolution

With no resolution-sapping optical low-pass filter, the E-M10 Mark III pulls about as much resolution from its 16-million-pixel sensor as it theoretically could. Its in-camera JPEG processing also does an excellent job of suppressing any potential imaging artefacts, so there’s no false-colour moiré or maze-like aliasing. At ISO 100 we see around 3200l/ph before the lines blur, with this value falling progressively as sensitivity is increased. But even at ISO 6,400 the camera still resolves 270 l/ph, before dropping to about 2200l/ph at ISO 25,600.

Below we show details from our resolution chart test pattern (right). Multiply the number beneath the lines by 200 to give the resolution in lines per picture height.
