...............and work on the Canon EOS 1D MK2 N?

If anyone can tell me I'd be grateful.

Thanks:thumbs:

You might be able to make it fit but I'd be wary of trying to do it. The DC on it means the lens is designed for the 1/3 crop cameras and it might jam/damage your mirror as it protrudes further into the camera.

I have seen images that show it does work. 3rd party lenses, unlike the canon ones, specifically designed for the smaller sensor do not have the 'EF-S' fitting canon created, as such do not have a longer back that projects into the camera body and interfere with the mirror operation. as a result the 10-20 does fit but you can't get much more than 12mm out of it due to harsh vignetting. I believe its 11mm is the limit. aside form that all electrical contacts work as normal.
Despite the evidence I would proceed with caution, remember - a 1dmkIIN isn't a 350D, if it breaks you'll be paying through the nose to fix it...and no one but yourself is responsible.
do a google and you should find the odd article about it

Thanks guys for the reply.

Is it the case that the 10-20 was built for the 1.6x sensors?

The 1D MK2 N is a 1.3x sensor.
Does that make a difference?

I am not going to risk using it until I know it can work without a hitch.

I've seen a sigma (or was it a tokina) UWA used on a film body. The result isn't damaging, but the larger sensor will mean that you'll have to zoom in slightly to fill the whole sensor with an image.

The sigma 12-24 works on FF (I think).

Anyway, it will fit, but it might have a black circle around the image without zooming.

The answer is a definite yes..

At least these guys did .. review with it on a 300D and 1D

"although it does vignette a little at the short end"

Answer - YES. so much vignetting that you cant use it on a full frame until 20mm - YES.

You wont damage the camera, but, if you're anything like me, you will get majorly annoyed with the results and go out an bu the 12-24mm which is AWESOME :)

Thanks for the help.

So are you saying there is no vinegetting with a 12-24mm?

Do I lose anything at the wide end?

There is a little light loss wide open as can be seen here (not being the best example due to being hand held on a traffic island!!)- but the SIGMA 12-24 is designed for a full frame. Remind me of the crop on the mkII N? Dont remember it being very much at all...... Either way, you trade 2mm at the wide end for a lens designed specifically to be used on any camera from 1.6x to 0x crop

DC lenses for Cannon are a normal EF mount and so will fit any compatible body. Unlike Canon's EF-S lenses which are physically different and have the problem you described, the only difference a DC lens has over a DG one is the smaller image circle.

Because of this it only really makes sense to buy a DC lens for a camera with an APS-C (1.6x) sensor, although if you already have the lens it can give you other options if you accept that you will need to crop images.

As already said, the Sigma 12-24 lens is the widest full frame lens you can get without going fisheye, and for a 1DIIN would be a better option.

Thanks for the advice.

I am gonna get out over xmas and see what the 10-20 can do on the 1D N and see if I can live with it.

Thanks again:thumbs:

This is what the 10-20 looks like on a 5D
not recomended

Jees - dont remember it being that bad - but then they didn't make it off camera with me:'(

Was that at 10mm? What aperture?

Cheers
