Ha! Thanks! Obviously I forgot to look 24 bajillion replies down for that information. Silly me.

As I thought - you have shot an almost flat scene. I'm guessing at f/5.6 or so - or, like I also suspected, you were a long way from the subject, hence no background blur to speak of. I can't tell as there's still no aperture or distance information. You also did not use manual focus as I suspected earlier.

Its NOT flat

If you REALLY want to make a useful test, grab your tripod, grab the three lenses and pick a scene - preferably one with a strong foreground subject and a wide aperture so that the background gets really thrown out of focus and create BOKEH. The scene you had there would work just fine if you'd have stepped forward by 2 metres or so.

I know what I am doing. I did the close range bokeh test already.

Seriously, how can you call that image a bokeh test when the whole thing is practically in focus? That's not a bokeh test at all, that's just a test of how the lens renders almost-in-focus circles of light in the corners.

yes it is a bokeh test for harsh background condition.

I would GENUINELY be interested in seeing your Canon 35mm f/1.4L II vs the Mk1 and the Sigma if you actually shot anything remotely like a real bokeh test.

I believe you.

Cheers,

Mark.

Whaaaaaat?? put your cursor on the image, it tells you the exif...... f1.4

Perhaps you don't know "bokeh". The scene is NOT flat!! I am testing the lens to a more extreme condition.

I am not interested to see the bokeh when the subject is less than 1 meter away from the camera. I know in my mind both lens will do well.

I know you are impatient but please do navigate around to find the answer you seek. Everything is in that thread!

Perhaps someone else can help me explain to you why I shot the subject about 4 meters away to test the bokeh...

The flickr link in this thread was link to me by JACS.  My test simply confirmed the sigma couldn't handle bokeh in harsh condition.
