Sigma 10-20mm vs Tokina 12-24mm

In terms of sharpness, contrast and whatever else makes a lens better than the other (excluding focal length, speed [relating to f/stops, not USM] and weight), which gets your vote?

The votes can now begin .

I have the Tokina and it's forsale so I'm biased hahah...

Kidding aside, wide angle is great regardless of which lens but 10mm vs 12mm is a choice only you can make.

I went with the 12mm and I think it's really wide.

I would have voted for 'both are equally excellent' but it wasn't a choice. I ended up with the Tokina. I'd probably have been just as happy with the Sigma. Both are sharp, both are well built, and both are excellent lenses. The Sigma is wider, perhaps a smidge sharper, and has HSM. The Tokina is better built (L-class), is longer (don't discount this), has less distortion, and is constant f/4.

Both will do you quite well. I tested both, was very torn, and finally just got the Tokina, and I haven't been disappointed. Had I gotten the Sigma, I'd probably be singing its praises too.

Also, while there is a significant difference between 12mm and 10mm, I have never missed 10mm. I've never said 'I wish I could go wider.' I have said "I wish I could go longer without changing lenses." Honestly, 12mm is plenty wide for 99% of all wide-angle photography (sans fisheye), and this is coming from a wide-angle junkie. Probably 50%-65% of what I shoot is under 30mm.

I too had to make that choice, and bought the Tokina because of its built. It's a solid lens, if not a little heavy, quiet enough, and sharp. I also like the auto/manual ring, since I don't have to move my eye from the viewfinder to engage it.

i used to have the Toki. its an excellent piece of glass for the 1.6 crop cameras. the only reason i sold it was because i moved up to the 5D. although it fits the 5D, it severely vignetted from 12-20mm.

Sigma FTW can't wait till it gets here...

I voted Tokina, and i have not tried the Sigma. That tells you something about a photographer who is perfectly happy with his lens, but nothing about how it compares to the Sigma...

The votes are about even so far...

The Sigma comes with a pouch and hood which is nice.
The Tokina is constant F4 which is great as well.

Which lens will work on a FF body with barely any vignetting?

Tokina also comes with hood, no pouch though.

They both will vignette on FF until around 20mm or so. I know that the Tokina will vignette on the 1Dmk2 until 16-17mm.

Ooh both come with hoods, that is unexpected and very good news .

Now the choice is harder! Ahhh!

At the ultra wide level, even 2mm makes a BIG difference. i voted sigma. If i needed one of these, this would probably be the one. It is an EX lens, sigma's equivalent of L 'pro' quality - and a great price too.

Tokies and Tammies have never really turned me on. but since i threw caution to the wind and bought the sigma 30mm f/1.4 EX - I've developed a soft spot for the marque.

i use the siggie and love it..never tried the tokie but i hear its great also...as is the canon!

my vote goes to tokina

i'll vote for my sigma. i've never shot w/the tokina.
