Wow. The bokeh look really terrible. When will these third party manufacturers learn to stop making lenses with MTF being the only consideration. I\'ve spoken to some of Canon\'s reps and questioned them about their image quality standards for L glass and Canon would throw this lens design straight into the trash in 3 seconds flat.
Besides the onion bokeh, the bokeh blur is also really non gausian and harsh, almost having a sqaure falloff. No other major lens has such terrible bokeh falloff, it reminds me the old errors you saw with square bokeh falloff in older versions of Adobe Camera Raw which they patched. Shame you can\'t patch an optical design. When looking at their sample photos (those posted on lens rentals then sigma\'s blog) I could instantly tell something was not right for this lens even in the small images. I\'ve tried the Canon 1.4 Rokinon/Samyang/Bower 1.4 and the Nikon 1.4. All have fantastic bokeh and none of these problems. It\'s not hard to design a great 35mm lens.

Sigma 35mm 1.4 Sample @ 1.4

From speaking to Canon reps I learned that Canon put a hard limit on OOF highlight quality and lack of onion bokeh. The Sigma 35mm 1.4 exceeded those limits by a huge margin.
For comparison here\'s the 50mm 1.2L\'s onion bokeh. Which is kept to a reasonable level. The Sigma 35mm 1.4 is off the charts. I think anyone would agree the 50mm 1.2 is much less disturbing.
