'cept for 12mm raw vignetting is well controlled. Do you have a feel for how quickly it drop (12mm is 1.5 stops and 25mm is .3 stops.
Impressive consistency (for mtf) from 12mm to 100mm you could almost test it at one point and reuse the same graph (though edge resolution and to a lesser degree center resolution) is dropping slightly. Also very low loca in your bokeh shot.

Surprise the optics didn't perform better than 3 stars. True it is not as good as a good prime but hard to find a zoom that will beat it - esp a super zoom - can you think of one from any vendor ?
