Quite a beast:

However, despite the size, it's a unique proposition which I hope will give idea to other manufacturers.

I bet an equivalent FF (20-50 f3.4) or APS-C (13-33 f2.3) lens could be made smaller though.

I wish the pix of the lens were not taken with such wide angle lens. This makes it look even bigger than actually is.

The specs have leaked ...

Size/weight falls between the Oly 12-100 f4 and the Pany 50-200 f2.8-4.
Very expensive (was expected).
I'm really fond of the focal range though!
