Sigma 28-300mm f/3.5-6.3 DL Aspherical IF Hyperzoom Autofocus Lens for Nikon ...

Sigma produces lenses for different brands of camera's. The optics are the same, but the connection differs from brand to brand. So if you have a Sigma lens for Nikon, you won't be able to use it on a Canon or Sony. Unless you buy a adapter. But when you start using an adapter, you will lose the Af in most cases, because the electronic in the lenses differ also. and that can't be bridged.

Yes.

That depends on the lens. Sigma makes their lenses with a variety of mounts. If the lens has a Nikon mount then you don't need an adapter at all.

Since the Nikon lens mount has a deeper flange depth than other mounts, you cannot fit a lens with another mount onto a Nikon body without losing the ability to focus to infinity. Because of this, you won't find an adapter for another mount. Adapters are available to fit Nikon lenses onto other cameras but not the other way around.

That would depend on what you mean by "ok." Assuming you get the lens with a Nikon mount, it will fit onto the D40 and meter properly. However, the D40 lacks an autofocus motor and thus this lens will not autofocus. You can still focus manually.

This lens can work with 5D mark II ?

If it has a canon mount it should work fine

Hi It might work the way to test is to fit it 2 the D60 set the camera to av and a iris of F16/22 use the stopdown button if the lens stops down your ok if nothing happens it will need a rechip but I think the the rechips are no longer avabil

In the uk if you have a receipt from new it will cost £5 But no receipt or second hand it will cost £33.99

To NOT get that error you need to use in AV mode. It's the only way that old Sigmas work with the new Canons. It's an aperture bug that old Sigma lens have and some the only way to fix it is to rechip it. The problem is that Sigma no longer rechips the lens.

The part called the interuper is braking the iris will work at some parts of the zoom but others the iris will stay close it need the interuper replaced
