>>3200867In terms of depth of field, the Olympus is at a 2 stop disadvantage.
In terms of ability to shoot in low light, the Olympus is around 1.5-2 stop disadvantage because the Sony can make up a loss of aperture with an increase in ISO at the same noise level.
So an f/3.5-5.6 normal zoom is a closer equivalent in actual practical usability to the f/2.8. So more like this.
