We are very far from the quality of a 24/70 - F / 2.8 Full Frame, for a price that is not quite so far. DxO analyzes confirm, it is paradoxically best large aperture between f / 2 and F / 4, but you are urged not to close imperative beyond F / 5.6 to sharpen distant, you would get the Conversely productive, because the sanction of diffraction is immediate. This is the compromise that must be accepted for portability of the Micro 4/3 concept. The laws of optics are final. So yes, in its domain, it is excellent. But do not ask and do not go compared to a 24/70 FF too quickly as do some critics who surf the micro 4/3 marketing mode.
