Tokina 12-24 and 1D?

I'm just about to get a second hand 1D Mark II. Until I get rid of my Tokina 12-24 f/4, will I be able to use it with the 1-series camera? Probably not at 12mm, but except for that?

i think 16mm and up its ok

I know it works on full frame from 18mm on, so I'd guess it'd work at around 15mm on 1.3x.

OK, also with AF?

Yup. I've used on my film body, so that's how I know the full frame parts. Shouldn't be a problem on 1.3x, except for the vignetting wider than 15mm.

I don't see why not. I've used my EF-S 10-22, EF-S 60 macro, tokina 11-16, and sigma 30 1.4 on the 1D3 all without any AF problems.

There shouldn't be any difference in electronics between EF and EF-S systems. The differences are physical.

To be fair, the Tokina (and all crop lenses except Canon's) are all EF mount anyway, not EF-S.

Here is a shot taken with the mentioned combo at 15mm:
