The lens arrived on Friday and I had time this morning for a quick walkabout. Very cool so far.

I am finding the 10-24/4 to be an excellent buy.
It is highly rectilinear.
I realize that statement needs clarification because ACR automatically applies Fujifilm's on-board lens correction parameters upon import. I have used four other utra-wide zoom lenses with Nikon DX and FX bodies. My work requires straight lines at the frame edges to be straight. All these lenses' images were corrected automatically upon import into LR. The 10-24/4 Fujinon is the only one I would use at its shortest focal length without hesitation. I suspect this is because Fujifilm is very good at estimating parameters for second and third order barrel distortion effects, or the lens itself has a low level of second and third order barrel distortion effects.
It doesn't matter to me because I'm only interested in being able to use the lens' widest angle-of-view when I have no other choice. With the other four lenses I had/have to avoid using the widest angle of view because straight lines do not look right unless you increase the focal length by a 2 mm or so.
I also noticed the 10-24/4 is more susceptible to flare at 10mm than at longer focal lengths 14 to 16 mm). The same goes for transverse chromatic aberrations. Using LR 5.X the lens CA correction in LR improves the borders of high-contrast regions (blue sky and window frames/panes) at 10mm. This is not necessary at longer focal lengths.
The lens is very sharp. The XT-1 and 10-24/4 handle sensor overexposure very well. The purple/cyan fringing level is low and border detail of objects like window panes/frames against an overexposed sky is very good.
The fly-by-wire focus collar is the best Fujifilm has produced so far. I experimented with using AF and manual focusing and found while the AF is fast and accurate, I preferred using the lens collar with focus peaking. It's quicker to optimize the DOF ( I try to use the widest possible aperture to increase the contribution of off-camera flash light) I can't tell any tactile difference between using the 10-24/4 focus collar and the 16-35/4 G Nikkor focus collar (which is mechanical).
The 14/2.8 Fujinon is a bit sharper (especially at the edges) than the 10-24/4 at 14mm. But I have to waste time pixel peeping to see the difference.
