I am not impressed by the sample images I've seen. I don't know if it's just bad in-camera processing or what. Take a look at this sample picture...click on the Original and look at the blond hairs on the horse as well as the brown hair on the forehead: http://www.dpreview.com/galleries/reviewsamples/photos/2736804/dsc00045?inalbum=sony-alpha-7r-samples-gallery

surapon, I love your self portrait in the bathroom mirror. If I saw this image in any other context, I would want to know the story behind it!

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.

You're welcome! Also 1.2 is only a half stop faster than 1.4.

I didn't read all the comments on this post, but this page is incredibly useful for these sort of common errors:

The 50L is front focused. It seems longer?

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

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.

Sigma 85mm 1.4 @f/1.4

All three were taken from the same spot.

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

I've used the Sigma for a few years and have been really happy. I just got the 1.2 on Friday and so far it's so close to the Sigma that I'm not sure what I spent the extra money on. I plan to do a full comparison in the near future though. Here are two shots taken wide open. The Sigma is a bit shorter than 50mm, but not as much as these images would suggest. I believe I was a little further back with the Sigma.

My initial impression is that the Canon is definitely better. I'm not convinced that it's 4x the price better.

Both are definitely a step up from the Canon 1.4 when shooting wide open.

EDIT: replacing attachments with larger versions:

Pricewatch Deals / Re: Have you ever purchase camera gear from BuyDig.com

I've made at least 6 purchases over $300 there without a problem. I bought the 100 L macro most recently.

I ask this in all seriousness...not try to start a flamewar...

Why would you install Windows? Is there a video game you play that isn't available on OS X? Follow on question...why Windows 8.1?

I've been a big fan of Sigma lenses and regard my trio of 1.4 primes as near perfect. This lens is really tempting as a walk around lens with two caveats: lack of weather sealing, and telescoping lens barrel. I went from the Canon 24-105 to the Tamron 24-70 2.8 VC and have been very happy, however I'm expecting big things from this Sigma in terms of IQ. I can't wait for the reviews!
