1) to MFT with the general exchange of 6D I wanted an easy equipment
2) In the telephoto zoom range I've always worked only sporadically, the focus is more in the normal range between 24mm and 70mm KB (so perfect for 12-40 2.8). The telephoto zoom should only supplement.
3) This lens is small, light and fully satisfactory from the picture quality.
The processing is made entirely of plastic, but I have not found that it thereby should be unstable, as if it were made differently. It wobbles nothing that gaps like and the picture quality is very good.
Why it has not become the great 40-150 2.8?
It would have led my transition to MFT absurdity and I had again a large and heavy combination, although the intensity is very tempting.
However, as I only use the additional telephoto, the lens smaller enough perfectly.
Price may be the difference not to mention jumping yes eye.
