i think canon mount is bigger....

 

[luddock]

Ya, the throat of the Canon mount is significantly larger than that of the Canon. And if using the original Sigma rear lens cap, it is also denoted which mount on the underside of the cap.

IIRC for Nikon mount, the contact pins are on the side of the lens but for Canon its on the bottom below the rear element.

Not really "significantly larger". From here it is 7mm (yes millimeters) and the registration distance difference is 2.5mm. That is why you get a lot of adaptors for the various mounts available.

There is no converter for Canon to Nikon as the registration distance means that you will not be able to focus at infinity if you try. It is as if there is an extension tube attached to it.

In any case, all modern Canon lens (EF-mount) are all driven by electronics. With an adapter, you can't set aperture, you can't AF nor use IS (no power). For Nikon to Canon bodies, the non-G Nikkors have an aperture ring.

I believe and there is a shop in USA that does conversion of canon mount to nikon but once covert it cannot be mount on canon. :dunno:

The shop name is as follow
Tempe Camera Repair Incorporated
606 W University Dr
Tempe, AZ 85281-3410
(480) 966-6954

I am currently using nikon lens on canon body, cost of the adapter is 150~200.

YMMV

if you are refering to the older Tamron lenses, there is such a thing as an adaptive mount.
the lens is universal. just get the correct mount for the respective brand.

Is it something like M42 (IIRC)?.

For Sigma, the non-DC Nikon mount lenses will have an aperture ring while all Canon mount lenses have no aperture ring. Do note that newer Nikon lenses eg. DX, G series do not have aperture rings.

Nikon mount lenses have a protruding lever at the lens mount for stopping down of aperture while Canon mount have none.
