Re: sigma 30 bokeh sample please

I compared the Sigma 30 out of focus areas to the Zeiss 24 (at f/2; not f/1.8) on page 2 of this discussion:

I don't think people are buying the Sigma for the bokeh; rather, I think they're wanting the sharpest native lens on the NEX.

Cropped a bit but here is a bit of what this lens can do with a 5n.

Same scene, the first is in focus, and the second is not.

Re: sigma 30 bokeh sample please

Would you also by chance have compared Sigma 19mm to Canon/Nikon 20mm/2.8?

No. I haven't used either of those lenses. 24mm is about as wide as I go other than fisheye.

I agree, I don't think that it easily surrenders the dreamy hexagons of the e50, and sometimes the bokeh has been rather too aggressive, just a little up the f range, the background is starting to softly defocus without competing with the center stage:

not bokeh, but sometimes a soft subtle background is better than lots of squiggly lines aka bokeh.

Re: sigma 30 bokeh sample please

I probably posted this earlier, but it does show bokeh with the Sigma 30. This was wide open at f/2.8 on a NEX-7.

Re: sigma 30 bokeh sample please

I'm interested in the bokeh comparison between sel1855 and sigma 30mm. Would anyone be able to post examples for a quick comparison (ideally of the same subject from the same distance). Thanks in advance.
