For the most part I think it looks decent; better than canon 35f2.

It certainly is quite a bit worse than the canon 35mm f2. the 35mm f2's problem is a 5 sided highlights (when stopped down, obviously), but it has no double line nisen bokeh background problem that this Sigma displays:

In reality the 35mm f2 from canon has quite benign bokeh (I should know... I use it with shallow DOF a lot). not the best, but surprisingly good. Obviously you singled out the Canon 35mm f2 from the list I gave because that is the lens I own <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt='' />/>



Showing quite smooth transitions without a nisen bokeh character wide open:



Stopped down still smooth bokeh, and showing characteristic 5 sided highlights:



Smooth transitions from focus to background blur without double lines, 5 sided highlights obvious:



And more smooth bokeh with no hint anywhere of double line nisen bokeh:





Bokeh wise its main vice is that the 5 sided aperture, when stopped down, can make nasty patterns with lots of highlights.



I do not see such a benign bokeh with the Sigma 35mm f1.4.. Not with the leaf images, not with the Sigma provided images.
