The 45er is in my view a great complement to the 12-40mm standard zoom. It is very small, weighs little and through the large aperture of the "free parking disadvantage" of the small sensor is the MFT offset.
The image quality is for me to the best of my lenses (Pana, Leica, Voigtlander, Canon L etc). The images are particularly sharp in the center, the bokeh is nice and round and for me as an amateur photographer are not aberrations recognizable.
The autofocus operates as fast and accurate as with the 12-40mm and therefore absolutely perfectly.
For portraits and for highlighting the 45er is therefore ideally suited and priced at MFT also a real tip.
