Thanks for posting this as I have been wondering if this DTC option is any good.

Sadly from what I see there it's not so good - the 40-150 beats it by quite a margin...

40-150 left, 12-40DTC right

Naturally there is a difference. The 2x DTC takes a 4MP crop from the centre of the sensor then interpolates it up to 16MP. So you are comparing a 4MP image with a 16MP image. Good enough for up to say 8x10 inch prints but no bigger.
