Im in the market for a 35mm for my 5DMK3.. Out of the option which is best wide open for nice bokeh??

The critical part of the bokeh is when the blur is just a few pixels wide. Once the radius is large enough, you are not going to see much difference. Unfortunately, those are the typical examples of "good bokeh" often presented.
I would study the Flickr groups. IMO, Sigma pushed the design too much, and to gain sharpness, they compromised the bokeh. The Canon has its problems with the bokeh as well. To make things worse, the typical double lines might be maximized for radially oriented lines, and minimized for perpendicular ones, for example. So one comparison can be misleading.

It depend on how the spherical aberrations are corrected or not. See p.36 here: http://www.zeiss.com/c12567a8003b8b6f/embedtitelintern/cln_35_bokeh_en/$file/cln35_bokeh_en.pdf.
Also, see the conclusions on p.40, in italics, the pictures on pp. 41-42, and the comments there.
There is a reason I warned against making generalizations from one comparison only. Here is an example of less than excellent bokeh:Mt Spokane Photography said:Optically, the Sigma looks very good, and the bokeh is excellent.
Eldar said:The only non-L lens I have is the Sigma 35/1.4, which I bought just to check if it actually delivers what the reviews said. And it does. The only other AF alternative is the Canon 35 f1.4L, which has received a fair share of criticism for being outdated. But if you drop chart reading and just look at the images that lens produces, you´ll see some stunning stuff. The only alternative beyond these two is the manual focus Zeiss. I have not used this lens myself, but it is difficult to imagine a Zeiss lens with poor performance wide open.
I have attached a picture of the local lion, shot with the Sigma wide open.
Which lens is this? I have used the Sigma extensivly for many months under very varied conditions and I have not seen anything like this. I would rather say that it produces very good bokeh compared to the other lenses I have. And most people would rate them as good.Pi said:There is a reason I warned against making generalizations from one comparison only.

You must have used a lens extensively to know its weak and strong sides. The bokeh performance can really surprise you in many situations.

Not only it is probably the cheapest high performing 35mm prime, it is right at the top, fighting for number 1 or 2 spot in all the reviews I could manage to read.
At the end I got one and I can´t be happier that I did not get neither the zeiss nor the canon´s equivalents =)
MonteGraham said:Thats what im reading too. But what has me leaning towards the Canon is of course the "Canon" name.. Sometimes 3rd party lens scare me for the future. You know Canon is stingy with their technology. so im not sure if a 3rd party lens will become obsolete 2 camera bodies from now. The only way i would jump in on a 3rd party is if it was that much better!! but from what im reading it neck and neck and to me the future wins out all the time. im just looking with real world advise from someone who actually shot both lens and can give me a honest critique on both.

TommyLee said:clearly for me the 35 sig is waayy better than my 35L (was)...
I sold the 35L BEFORE the sigma...and loved that canon a lot...
then I tasted a ... sharp-wide-open.... lens with little fringing/CA.....the sigma...
now I am really spoiled...
used my 24mm f1.4 mk I last night and ...uh ...I forgot how weak it can be wideopen...
nice but ..it ain't a sigma 35 class of lens.... I did try the 24L II and it was a bit better on a few rentals....
but not like this sigma is....
if the sigma 24 rumor is true...I will try that one too
I might add if CANON finally redesigns / releases the 35 II ...they DID NOT release (when they saw the new sigma) ...if it is better - I will get it...
I await Canon's move on this

Mt Spokane Photography said:Its a matter of opinion, there is no measurement of bokeh. Generally, round is a good start, but there are so many things that can be evaluated, cats eye, onion skin, and as in your example, LoCA..
