so the Sigma is for crop bodies only? Why would they do that? Seems like it limits their market.

They can create a smaller lens by just targeting crop sensors. A smaller size appeals to many users.

I have never had to dial in a single MFA number on any of the Canon lenses I have owned (L or non-L), I really don't understand how people have so much bad luck with Canon. Could it be your body that is not calibrated or mine that focuses better (5D3)?

Sorry, I didn't mean to just come in and bring in all this negativity. But you have to understand how I have tried SO MANY sigma lenses over the course of years and never got one that actually worked properly.

I guess I am kind of in the middle here. I've had or used about 15 different Canon lenses. Never needed MFA on any of them. I also have a Sigma 70-200 2.8 OS, Tamron 17-50 & 28-75 and had a Tokina 19-35. None of them ever needed MFA, either. I shoot a 60D. I must be the luckiest guy in the world. Or perhaps my aging eyes can't discern an OOF photo anymore. NOT!

EDIT:
I would be interested in the 18-35 if it were either wider, which would make it harder to make, or made for FF bodies, which would make it huge. I'll pass. Still considering the 24L II, though.

The 18-35 destroyed the 24LII in terms of sharpness, just check the link posted by OP.

f1.4 vs f1.8 is negligible, and you have the converience of a zoom @ less than half the price!

No brainer to me...

Are there any photos posted? Would love to see the bokeh it produces at 35.

It just seems like a lens of that quality and at 1.8 would be marketed toward pro's with FF. I shoot a 7D and my 16-35L is my go to lens. Really just wondering out loud....thanks

it saves money, and brings costs down...on a 7D there's no reason to really stick with the L instead of the sigma...if you look at all the test results, it's better wide open than the canon

here's a few:

i'd expect there to be more in time...

as for the lensguy's sigma hatred...just stop clicking on threads that have sigma in the title...you'll be happier...it also is hard to take someone seriously when you don't see a single photo posted in a photography forum...and i get that it'll be hard to now, because everyone will be negative, hell you'll probably be negative about any of my shots now just for addressing the lack of photos

Have you not seen his collection of wall shots and fuzzy lens cal charts? They are amazing! I personally am a fan of the way he uses that vignetting to his benefit.

C'mon guys, let's be fair here, the lens guy's shot more walls and rulers in a week than any of us in our entire lives! I think he's more than qualified to tell us that canon lenses shoots walls and rulers better than the sigma counterparts, haven't you seen those 800% white wall crop samples?

Everyone is onto TheLensGuy now. :p

My experience is mixed with the Sigma 35. I have to say this lens produced some stunning images when I nailed the focus. But every once in a while I found some shots to be totally OOF. I know its not user error since with the 85L I always know I did something wrong if I get an OOF image, not so with the 35 - I just get completely OOF images even with the perfect techniques and its clearly reproducible under certain conditions. After some tests I realized it was affecting longer focal distances and only becomes noticeable with a shallow dof. MFA on camera was a never ending nightmare because when I got the long distance right the closer distance suffer. This wasn't completely a deal breaker though since I typically use much smaller aperture for subjects further away but it affected my user experience quite a bit. It was only after I got the USB dock that I solved this problem completely with a -8 adjustment for longer focal distance. Now the lens is simply phenomenal, sharp and has a fast and consistent AF.

So, has Sigma really completely solved their QA issue?
I would say no. The only experience I have with a Sigma lens is not as smooth as i had with my other Canon lenses. Who knows, maybe TheLensGuy has gotten more than his fair share of these nasty issues.

Has Sigma changed the game?
I think this is a resounding yes, despite my own experience. The Sigma 35 is currently my sharpest lens (I think I have some good lenses) and for about half the cost of the Canon counterpart. If a bit of USB docking session save me half the price of a lens, sign me up. Some people bash the construction of the Sigma, but to me the new line actually feel much better in build then some Canon L lenses. With the stellar review of the Sigma 18-35 f/1.8, I think it's pretty clear Sigma is now going all out offensive. As a consumer I cannot be happier as someone is finally offering equal if not better products at sensible price. The margin Canon and Nikon has been charging on these stuff is downright robbery compared. I am glad that someone is finally eating their lunch.

You can buy a $10,000 used civic, chip it and destroy 911s. That doesn't mean I will pick the civic over Porsche


So what your saying is you buy things to show off the emblems instead of what does the job best?

Just curious... Anybody know if this lens will work on aps-h bodies? Much like the tokina 11-16 works on aps-h with a bit of vignetting on wide end. Would love to get this for my 1d iii :)

Sigma is certainly innovating. I love crop cameras and the Siggy 18-35 may just be my next lens purchase.

And a $25,000 subaru impreza does 0-60 almost as fast as a $75,000 BMW M3, but they are totally different cars. For starters, BMW handles a lot better. Not everything is 0-60 times.

No sir it doesn't.

Ever think it was you, not the lens?
