I don't quite understand the expectation of a "cheap" 12-35 f2.8 m4/3 lens! Why should it be less expensive than the equivalent Canon or Nikon lens (half the price of the Canon lens)? Smaller size does not amount to lower price; the number of operations involved are most important and they would be no less than a FF lens. If this lens will sell at 900€ this summer, it is reasonable in terms of market levels. The equivalent new Tamron sells at 1200€!! If the quality is good, and it seems to be, given that it is a zoom, then this is a good deal.

Of course the size makes the lens much cheaper to produce. With smaller glass elements you have to use less expensive optical glass. You have to mould and polish much smaller elements. You can make more elements at the same time too, when they are smaller.
It is simple... big elements = expensive lens.
The price should lay between the price of a 28-70mm f4 FF lens and a wide angle zoom f4 FF lens.
