Any experience with Sigma 14/1.8 Art?

[Erik Lund]

Very nice! I'm looking forward for more from this UWSM, Ultra Wide Speed Monster

[Nikfuson]

A couple more. Eager to next test/show coma (which is present at 1.8-2.8 )
First here is field of curvature...pretty flat.

And another set, both at f/1.8.

Super wide with Bokeh it’s crazy, it’s a very unique  perspective

Unfontunately, I think this second copy is decentered as well:

The Australian Sigma distributor has a top end optical bench and checks all of the higher end SIGMA lenses for such problems before they are released to the retailers.  That says something I feel.

I wish there was an optical QC available here too.
On the other hand I've started to fear that maybe it is my camera that's at fault. Two samples and the same defect on the same side.
On the other hand II: I have the 20/1.8S at hand here...

BTW how do you like the 20mm f/1.8S?

I haven't done much more than mounted it until now. Will take it out for a spin as soon as the rain stops making life uncomfortable.
AF is dead silent and there is quite some vignetting. It seems really sharp (as to be expected).
Will report in a separate thread.
And...it has to really persuade me before I cough up 13.500,- NOK for this lens...

Very flat field performance, that's impressive for such a wide lens

Yes, an unique view.
