Seems like this lens is now shipping.  These results look pretty good:

Here is a quick test with the rise extended all the way @ f11

There is a lot of CA in that example, but it's a pretty tough shot.  What are your thoughts so far?

This was a prototype lens I tested, it was raining so this is a quick interior at Canon head office. It is possible that production samples have been tweaked although I don't know how likely that is. Compared to my 17-40 zoom or 24TSE, it had far less CA and virtually no barrel distortion or vignetting. Bear in mind also that @ 12mm rise this is an extreme angle of view, equivalent to half the vertical dimension of the frame. My 58 Schneider can't accomplish the equivalent on 4x5. Sharpness in the center about the same as the 17-40, but the corners were better.

It would be interesting to see how this lens performs with a 1.4x extender.

How useful is Tilt anyways with a lens like the 17mm, there is so much DoF anyways.

I would prefer the 17mm without tilt, it would be smaller and cheaper. The tilt can get you in trouble if it accidentally gets moved off center.

I disagree - the addition of tilt and swing opens up a multitude of opportunities that simply are impossible without a lens with movements. Both the new 24mm and 17mm TSE lens's apparently have a lock to prevent accidental movement.
