I tried google searching and found quite a bit of info on swapping ef to sa so I am guessing this is fairly easy but does anyone know for sure?

I am curious if you can actually make an SA lens work on our cameras

What's the point? Sigma makes lenses in EF mount.


Did you lose Digital Photo Professional (DPP)? Get it here (external link). Cursing at your worse-than-a-map reflector? Check out this vid! (external link)

Agreed...however, there's really no way to use a mechanical adapter as the Sigma SA mount has the exact same flange distance as the EF mount. You CAN however, do some mount conversion. If you're really bold, you can even hook the electrical connections up, as the Sigma SA contacts are the same electrical connections and instructions as the EF contacts. Some guy converted his Sigma SD-14 to EF mount (after quite a bit of work to change the mount), and it fully works...including autofocus and auto aperture.

That would be really cool to have a SD14 in EF mount..

The Foveon sensor has always intrigued me :)

because I have a chance to get a sigma lens at a decent price which I cannot get with an EF mount near that price

I contacted sigma they wont do the conversion :(

It's a shame that guy doesn't do the conversions anymore, I'd liked to have given it a go. If I tried it I'm sure I'd frag the camera.
