After photographing 5 years with the Canon 35 1.4L as a professional bide photographer from http://totaalfotografie.nl, I switched tot Sigma.reviewed December 30th, 2015
My first three copy's had a very bad focus issue and even the fourth needed a focus correction of +18 on my three 5D Mark III's.
After the calibration at Sigma the lens was perfect for the time being.
Sharp, nice AF, smooth and amazing bokeh.
But after shooting a while, this lens needed soms focus correction. I had to do it around 1 time a month. After the calibration the lens seems to be perfect again. I used Focal Reikan to calibrate (can't recommend this software of the crashes).
After photographing a year with this nice lens I went back to my Canon 35 1.4L. En guess what, a better AF in terrible dark places and always sharp pictures in stead of the Sigma.
The Sigma has some strange issues and as a professional who used both lenses en several copy's a long time I still recommend the Canon 35 1.4L.
Maybe a little more CA beneath f2.2 but 99,9% of my pictures are sharp again.
