In the november 2005 and january 2006 issues of "ColorFoto" 60 lenses were tested, for Canon EOS 20D/350D(XT) and Nikon D70(s)/D50.

They tested wide angle zoom lenses and wide angle "primes", among other lenses. The results show something very surprising, to me anyway.

The Tokina f4 12-24mm Asph. AT-X124 PRO DX outperforms or comes very close to the tested primes from Canon, Nikon and Sigma.
Some figures for the Nikon mount lenses, tested on a D70s (obviously the Canon lenses do not come into play here):
0. = tested focal length (line pairs per image height)
1. = sharpness open (line pairs per image height)
2. = sharpness aperture stopped down 2 stops
3. = contrast open (%)
4. = contrast aperture stopped down 2 stops (%)
5. = distortion (%)
6. = vignetting open (f-stops)
7. = vignetting stopped down 2 stops (f-stops)

I know the numbers are a bit hard to decipher and interpret, to make things a bit easier I have grouped them into 4 focal lenght groups. Do take into consideration that the lenses may be equal in focal lenght, but their max. aperture and therefore tested apertures vary widely.

What we can see is that for full frame film designed wide angle primes have it more difficult on a DSLR than especially designed for APS-C digital zoom lenses.

I have heard a lot of good things about the Tokina 12-24 f/4, so I would be surprised if it were not as good, or better, than the others in it's class.

I just wish there were a store around here that carried Tokina, so I could give em a try.

Thanks for posting the table.

I can't wait to get my Tokina 12-24, and this just makes me feel even more confident about my decision :)
