the sigma 35mm @ f1.4.... 5D3
I sold my 35L (which I liked) and bought this lens
the woman(mother) - on the left - in the background is a good example of a nice bokeh quality - to my eye...
the guy in right corner is pretty nice treatment too
of course the quality varies with differing back ground distance and foreground focus distance
and of course different busy shapes too.... the sigma is not tops...but pretty good IMO
this just seems to be an ideal combo for the sigma 35......
different distances...plus the stove-hood on left ...the lines start to get slightly busy.. the 85L would likely handle that differently
I believe...all this is pretty subjective...
lots of nice examples in this post
people here have really nice compositional ideas too...
I would say the 35 sigma and then - either - the 135L or 85L canon are a great pair..
the sigma is sharp wide open, has minimal distortion and chromatics,
is built solidly and focuses accurately and quickly .... it is a wonderful lens - IMO
