Sigma 10-20 v Canon 10-22 Tested

Another reason to go with the Sigma over the Canon is its (Sigma) abilitity to work on 1.3x crop cams. The only other alternative is the Sigma 12-24 which is slower,doesnt accept front filters and more expensive.

Thanks Jo!

The Siggie will "work" on a 1.3x body but it won't be pleasant at 10mm (maybe at 14mm it'll "work" all right). But indeed it's a good lens.

I guess it depends on one's view of vignettin or light fall-off. For those who see it as a feature/blessing will love the 10-20 on a 1.3x crop. For those who dislike the vignetting, I would suggest usin the 10-20 at about 11.8mm and above for non-existing vignetting affects

Jo,always a pleasure to visit your galleries and tests

Jo, could it be that the particular copy of the Sigma you used was not "top notch" ?

I say this only because ive seen numerous complaints about this particular series (10-20) on the internet. Majority of victims of QC post images to back-up thier complaints.
Thats why,when I bought mine, I tested it the same day I got it as the store I bought it from does not have a return policy but was willing to switch it out the next day if mine was faulty. Im not even 100% satisfied with mine yet. The quick tests I did were, well quick. It does have a full warranty, so if in the coming days, I notice any faults, ill send it in for fixing or replacement.
I in no way am implyin all Sigma lenses suffer from QC issues. I bought 3 bigma's so far. Each was as sharp, if not sharper, than the previous copy.
I guess its the UWA issue thats causing these faulty 10-20's.

It's interesting that all the emails and comments from folks that have the canon are "i'm glad i have it", and those that have the sigma are "i'm glad i have it."

as for the PP work, it was very quick and dirty. basic levels adjustment, slight USM, and a quick dab of nik color efex's "blue GND filter"

Superb, Nik do make excellent filters.

Two days in as a Sigma 10-20 owner and I am utterly in love with the lens. Its build quality is top notch and (maybe I got lucky and got a good copy) the image is sharp corner to corner with great contrast and minimal CA. From everything I read before buying I can see that the Canon has the edge, but not £200-worth of edge, the minimum price difference. For me it was more a toss-up between the Sigma and the Tamron 11-18.

I should also mention that, prior to getting this lens, the sharpest tool in my box was a £100 Sigma 28-105. These guys simply make good glass.

I also have the Sigma 10-20 and am very happy with it. In Canada I could buy two Sigmas for the price of one Canon. That's a significant difference. Plus the Sigma came with a hood and a nice padded bag.

Good comments, folks. As for QC and my copy, I'm of the opinion it's within factory tolerances; I'm quite pleased with it. No fretting here.

And yes Joe, you are correct: it does come with a nice hood and top-quality black EX carry bag (the Canon does not come with either).

I took the Siggie to the arboretum here in L.A. today and will post some shots from it (along with my 70300IS) later on at my site. Take care all and enjoy the light.

Thanks for that review.. I was at a toss up between the two myself..

I have to admit.. the brick walls, I prefer the Sigma's look.. everything other than that, the Canon looks much nicer to me.

I'll be going with the Canon.

Thats the reason i have mostly sigma in my bag.

Jojo, as always, a great and worthy test .

SoToMoSo,

does your statement mean that on your 1DII, the Sigma 10-20 gives good images from 12 mm focal length onward?

That would be great in my opinion, because it means the lens is definitely quite usable not only on the 1.6 bodies. (and give you the same 16 mm 35 mm equivalent that it gives on the 1.6x body).

Would you have an example picture taken with your 1D?

For some other tests (with MTF rating and examples) of both lenses, take a look at http://www.photozone.d​e/8Reviews/index.html

Best regards,
Andy

Andy, yes, from roughly about 11.8mm, I see no vignetting. Thats why I had trouble deciding between the 10-20 and the sigma 12-24. The sigma 12-24 is more expensive than the 10-20, but its FF not DC lens. On the other hand, the 10-20 is faster than the 12-24 and accept front filters as opposed to the drop-in for the 12-24.

Lastly, I decided that the 10-20 is better because it gives me 2mm from the wide end. Personally, there are times when I do not mind vignetting.

I will post some examples tonight or tomorrow at latest.

Ive been meanin to take some night landscape shots with the 10-20.

One of the real perks of the Sigma 10mm (or even the Canon 10mm) is that even with a FAT, CHUNKY 77mm CP, I noticed hardly any vignetting at 10mm wide open. It's nice to have the ability to use front-thread filters on these UWAs. I assume the excellent Tokie (being 12+mm) has no problem either. Now, disparate polarization across the frame, that's another issue (but isn't a lens fault per se).

I wish i had the money for either canon or sigma. Just don't have the $400 +

That's all right, for now use the kit lens and if it isn't wide enough, do some pano shots and use autostitch; it's free and works swell. Enjoy.
