To the OP...isn't the new Sigma 35mm f/1.4 the one that can be configured via a computer without having to send the lens to Sigma?  I thought it had the ability to adjust front / back focusing issues until you get it correct. 

Yes it is but the USB adapter isn't available yet (delayed a month or two) so I assume the OP has to make his return or keep decision before then.

So then is the canon 35l the better buy or should I pursue getting this lens adjusted? The quality is worth it not the money. I doubt I will shoot at 1.4 much more like 1.8 2.0 or higher just to have a walk about lens which is also why I was wondering about the 35 f2 is but the reviews do not seem so glowing.

I sent my 35mmL to Canon because it required +17 AFMA on my 1D MK III.  Its now very close on all my cameras, and is excellent, even if not quite reaching the sharpness of the Sigma.  It focuses fine as well.
 
You risk sending the lens in for adjustment either way.

In luck

Talked to sigma and there is a repair facility 35 min away and i can drop off my body and lens for calibration. Perfect cannot ask for a better option.

keep us posted. i'm a very happy sigma 35mm user, but i've had some very poor exp with sigma sercive in the past, so i really hope they've turned things around.

are you sure it's front focusing?
at 1.4, your DOF can be minimal (depends on the distance of subject)
here is a calculator for you

Update on Sigma 35mm. I took it in locally and they saw I was AFMA to +10 and they actually put it at about +15 internally so my camera is spot on and I am at 0 in camera. That makes this lens that much sweeter. Glad I took it in. If you buy a Sigma and it seems off send it in is my advise.

At some future point, you can pay $$$ for a tool that will let you adjust focus accuracy of the lens so that it may match what you already paid for.  Sigma has promised it, but hasn't delivered it.

About two weeks for $59 with software. Not too shabby.

Congratulations KKC. I know you're going to love that lens.

It's nice of Sigma to actually deliver the USB dock, but the fact is Sigma should tighten up its QC process so we don't NEED to use the dock.  Still, I am glad to see this safety net of sorts from Sigma..

I finally got my hands on a Sigma and tried it today. I liked the sharpness , although that wouldn't alone be at all a reason to sell mye 35 L. I like the built quality, but not the weight and size
Compared. I really liked the color and contrast and the bokeh seemed similar. The
BIGGEST QUESTION for my wanting to test it was in terms of AF speed, all info I have found point to the direction that they are very much a like, but that's
Completely false, it's WAY slower, very dissapointing. I haven't done any research if the 35 L is faster on the 1dX and other people have tested on a 5d not seeing the difference. But on the 1dx at least the AF of the Sigma is much slower and to me, that will always be what I look for in a lens.

Get the 35 L sharpness is a result of a properly focused image.

nonsense....
if the lens does not deliver the optical sharpness, no focusing will solve that.

well canon should be the first then to make lenses that need no AFMA.  ::)

My copy is outstanding, as sharp at F2 as my 50L at 3.5 and more so generally, and colours are great. Also in AI servo its spot on.. do a lot of skateboarding tracking sequences its actually much much more accurate than my 50L and 85L.
You may have a bad copy then, go back to shop and get them to compare it instore with a couple of other copies.

+1 on that, I was thinking the same thing!  If Sigma should be tightening up it's qc to avoid needing the dock, how much more at the price should Canon be tightening up their QC so we don't have to spend all that time MFA'ing our lenses?  I'm glad I can MFA my lens's.  If I had the Sigma, I'd probably be glad to have the dock!  ;)

Lol, yes I would much rather have a lens that is veryvery sharp but can't focus over a lens that is very sharp that focuses perfectly with very fast
Movement every single time .
