"" I think the only lens I would possibly trade this Sigma would be Canon 50 mm 1.2L""


I had the Sigma 50 1.4 before buying the Canon 50 1.2L a little over a year ago.  Overall I found color rendition to be better with the L lens then with the Sigma one...Now because it is much heavier then the Canon 50 1.4, not sure I would get the Sigma over the Canon 1.4 if I did not have the 1.2 already.
1DX, 24mm f1.4L II, 35mm f1.4L, 50mm f1.2L, 85mm f1.2L II, 135mm f2L, 24-70mm f2.8L II, 70-200mm f2.8L IS II :  D800, D4, and a whole bunch of Nikon lenses

Here's something to consider. I do almost exclusively outdoor shooting and have several expensive ND filters to be able to hit the max 250 flash shutter sync speed wide open
could you show me few examples (pictures) of this technique? I wonder what is it for.  ::) Thanks a lot.
I think that's probably way beyond the scope of this thread, but here's a link to the strobist web site that explains how the process is done: http://strobist.blogspot.com/2010/06/using-nd-filters-to-kill-depth-of-field.html

For crop sensor a good alternative lens for giving 50 mm field of view is Samyang 35 mm F1.4. It has similar performance than the Sigma and has the best manual focus ring of the lenses I have used. It has also build quality and robustness comparable to a big Canon L.

Just received a Rokinon branded Samyang 35mm and very pleased with it. I did the Nikon mount and use a Nikon to EOS adapter with AF confirm chip. I got a great price on it and figured I'd rather do an adapter than get a Canon mount and try to afix an AF confirm chip to it. I've only shot a few shots so far and I'm impressed with sharpness at f/1.4...better than my Sigma 50 at f/1.4. The lens has an excellent build quality, reminds me of the 100L.

Note about manual focus: With a AF confirm chip you can shoot in aperture priority (which I almost always do anyway) or manual with floating ISO. Plus if you run Magic Lantern unified, you have the choice of focus peaking in live view (paints in focus areas) and also focus trapping in non-live view.

With focus trapping you half-press the shutter button then twist the focus ring while keeping the selected AF points in viewfinder on the desired target. As soon as it is in focus, it takes the shot. Very fast and effective when shooting in Av mode. Note it requires MFA to be set which of course is off by a mile due to thickness of the adapter. Hopefully the programable EXIF adapters have enough MFA programability to deal with it (which I would assume they do otherwise why put it on there?). I have a fixed EXIF adapter now but have a programmable version on the way and will post findings when it gets in...
