Canon 1.2

So the sigma was shot at f/1.4 and Canon shot at f/1.2? 
Even if the shooter moved a little, there seems like a huge difference in focal length  :o

I'm in the same boat as the OP. I am rebuilding my set of primes (non-L's) and I'm taking a good look at the 1.2L.

I have a strong desire to get a good 50mm soon and it's an agony to wait for the 50mm f1.8?/1.4? IS USM, which has a CR1 rating:
http://www.canonrumors.com/2013/10/a-new-50-coming-soon-cr1/

I want to see first how the new 50mm will be, before making a decision between that and the 1.2L. $1700 + tax
 (even minus the rebate of $180) is a boat load of money.

If you could hold on a little bit more, maybe you could save at least 800-900 bucks. But that's still months away.

For now I'll try to get most out of my new 35mm IS (if I can).
5D Mark III, 24-70mm f/2.8L II, 16-35mm f/4L IS, 100mm F/2.8L Macro, 600EX-RT, Powershot SX50 HS, Sony a6000, E 16-50mm, E 55-210. And many batteries.

The 50L is available now from the major vendors for $1,439 (you have to put it in your cart to see that price). After the rebate and 4% BH credit, the effective price is $1,201!

Yes, the Sigma was shot at 1.4 and the Canon at 1.2. I will shoot some direct comparison images and post today.

Sigma 85mm 1.4 @f/1.4

All three were taken from the same spot.

A couple of comments on the above images...

Lightroom default processing of RAW files from a 5D Mk III... no tweaks.

I don't think I hit critical focus in the image from the Canon. I haven't done any focus calibration with that lens yet, but it should have been as sharp as the Sigma 50mm. Live view manual focusing shows similar sharpness. The Sigma 85mm is the sharpest lens of the three. When you step back so that it frames the same as either of the 50's, the images from the Sigma 85mm are much sharper at all apertures.

Canon 50mm 1.2L @ f/1.4

Thanks bchernicoff for the comparison.

The Sigma seems to be sharper. 50L has better color and contrast - better background.
ML: A7s + FE21 f2.8 -- FE28 f2 -- FE55 f1.8
DSLR: 1Dx + 85L II -- 200L f2 IS -- 400L f2.8 IS II

The 50L is front focused. It seems longer?

Is the WB set to the same number?

Hi I'm stuck deciding if I should upgrade my 50mm 1.8 to a 1.2 or go with the 1.4, I've done some research and read that the Sigma 50mm 1.4 is a better lens than the Canon 1.4. If you have had any of these lens any advice would be great to help me make my decision.

Since no-one else seems to have done so yet, I might as well give the obligatory warning re the Sigma, i.e. that you should be prepared to try several copies - this lens seems more prone to sample variations than most.  The copy I bought was so terrible in every way (it didn't seem to want to focus on anything, not even the wrong thing) that I found it annoying; I decided to stay with my Canon 1.4 (which is just fine) and not seek a better copy. 

What do you want the lens for? The 1.2 would likely be overkill (or even pointless) unless you're into very shallow focus effects.  If you're not, the Canon 1.4 is a very good lens - though it might be worth waiting a bit to see whether rumors of a new Canon 50mm IS or an upgraded Sigma 1.4 pan out.

The Sigma is more like a 46mm. At least that's what I've read on this forum and others.

Thousand Thanks, Sir, Dear Mr. bchernicoff.
From your Test at F= 1.4 both lens, My decision is to keep My Dear Sigma 50 mm F/ 1.4 and Not spend my money $ 1619 US Dollars for That Beautiful Canon 50 mm F/ 1.2 L.
No, Sir, Not worth 4 time of the cost of my old Sigma, just one stop faster and better Contrast/ Better Colors that my Old yes could not see the difference.
Thanks again, Sir for your great Job.
