I want two more lenses go go along with my 24-105L on full frame:

Sigma 12-24
EF70-200 f4L

Also, what exactly is so special about Sigma DG lenses? I couldn't understand from the explanation on their web site:
>These are large-aperture lenses with wide
>angles and short minimum focusing distances.
>With an abundance of peripheral illumination,
>they are ideal lenses for Digital SLR Cameras
>whilst retaining suitability for traditional
>35mm SLRs.

DG Lens
The most suitable lenses for 35mm film single-lens reflex cameras, as well as for digital SLR cameras. Sigma's development of the DG (Digital) range of lenses has concentrated on the correction of distortion and aberrations. Magnification of chromatic aberration is particularly conspicuous with digital cameras. The optical designs and cutting-edge technology incorporated by Sigma eliminate flare and ghosting from te image sensor and create excellent color balance. Vignetting is minimized whilst marginal illumination is ensured. These high performance lenses are equally suited for digital and analogue cameras.

Sigma DG does not mean anything special.

They are lenses designed for 35mm but with improved coatings for digital. They will work for film, full frame or crop.

Sigma DC is made specifically for crop and can mount on film or full frame but you will have black halos.

black halos are the new vignetting

Go Canon 10-22 over the Sigma 12-24.

OP here, I used to have the 10-22 but it won't fit on a full frame camera. I think the 12-24 would be EXTREM WIDE ANGLE like Beethy but better.

12mm's pretty much the widest you can get, yes? [In before "But it's closer to 13mm and it has distortion!"]
