I know there are a lot of Sigma 50 vs. Canon 50 threads, but I hoped to limit this one to crop cameras only. For those on a cropper, do you see a real difference? I have both to test and frankly I'm having a tough time. I'm only keeping one (or none) and have no plans to go full frame any time soon. Are the virtues of the Sigma lost on a cropper?

Both lenses. Obviously the Sigma is much larger. As one would expect, it's also quite a bit heavier. Is the extra glass needed for a cropper? I suspect not.

Here are some examples:

You may be able to tell, but the Sigma is slightly wider than the Canon. If the Canon is a true 50, then the Sigma is probably a 48. Here's a shot with the Sigma slightly cropped to match the Canon's output.

So am I missing something or do you need a full frame camera for the Sigma to really shine?

OK. So here are some extreme crops of the 1.4 shots.

Sigma at 1.4

In these examples I would agree that the Sigma is somewhat creamier while the Canon reflects slightly more detail.

I like the sigmalux better(lots) on ff(5dm2). On 500d it is about the same only cropped 1.6x. Focus was better as well. Thinking of buying a 5d or 5d2 again just for this lens.

Or get a 30mm 1,4 sig. Undecided.

That's the way I'm leaning.

If I wasn't hoping to get a FF in the future to shoot low light I would definitely get the Sigma 30 1.4.
The wider perspective works for what I want it for and the 30 seems to be a winner.
As it is, I hope to get a Sigma 50 only because I have heard a few AF problems with the Canon.
Hard to judge how real that concern is though. :confused:

Thanks for posting the images, very helpful for me. :D
The pics look pretty similar to me, similar enough anyway.
I do have some 77mm filters so the sigma works for those.

Thanks again,
Tim

Nice post....I think the bokeh from the EF in the first set of images makes me dizzy....The Sigma is creamier and basically that's what you're paying for along with the HSM and EX build. They look about even everywhere else. I love the Sigmalux on my FF and crop.....Just that the FL on a crop at 50mm isn't too useful for me. Whereas the 50mm on my 5Dmk2 is perfect for a walkaround.

Thanks for this, after seeing this thread I don't feel so bad about getting the Canon instead of Sigma. It seems like everyone is always badmouthing the Canon and praising the Sigma, but the difference isn't really that huge.

Right, they're both good lenses that can produce beautiful results.

They look really close. If pressed I would give the sigma a slight edge as far as color/contrast/sharpne​ss. That being said, the difference is minute. In the real world you would not really notice it. I have the Sigma 30 and love it.

Then why the knock against Canon? Just because the Sigma lens looks and feels so nice?

These comparisons serve to reinforce my decision to just stick with the Canon lens.

I'd already reached that conclusion with other close comparisons I've seen elsewhere. I just don't see enough difference to justify the extra expense, added weight/size of the Sigma, which may or may not work with future EOS cameras (there are no guarantees w/3rd party lens, there are some with Canon lenses, but this may be a moot point if the manufacturer provides updates if needed, as Sigma has done with some lenses in the past).

The huge filter size of this particular Siggy isn't a problem for me, since other lenses in my kit use 77mm so I have those with me. It's surprising to see a 50/1.4 require a filter larger than Canon's 50/1.2L, and a whole lot larger than the EF 50/1.4. (Some other Sigma and even Canon lenses use filters I don't have in my kit: 62mm, 67mm, 82mm so I'd have to allow for buying those as well. Just UV and CPOLs mostly... but maybe some portrait filters, plus an adapter to allow ND Grads to be attached. There's some added weight/complexity hauling around additional filters, too.)

The Sigma is a lovely lens, no doubt about it. Well made and good performing. I can see why people choose it. It's always impressive to any seasoned photographer to see a big old chunk of glass like that on the front of a camera! And it comes with a hood, while that's a separate, additional accessory for the Canon. I just hope Canon takes up the challenge and finally comes through with an overdue update of the venerable EF 50/1.4, without ratcheting its price through the roof.

Did I knock the Canon...? Did you read my post? I said nothing about the Sigma looking and feeling so nice (I only said the bokeh is creamier, the build is better and the HSM is nicer than the Canon, other than that...a wash)...get or keep whatever you want...
