Yes
Hey guys,

I'm pretty sure that the answer is no...but does anyone know of any way of converting the newer canon EFS lenses to the previous EF mount?

Would save me a few hundred pounds for a super-wide angle as I've just got hold of my 1st full frame.

Fingers crossed,

Thanks guys
 
There are on-line tutorials for modifying the mount.
BUT as they're designed for the smaller sensor they are not going to cover the whole sensor at all focal lengths, meaning they're not that useful.
 
even if you could it would be an exercise in futility because most of the EFS lenses are made specoifically for a cropped sensor so have a smaller circle of view than an EF lens so you'll wind up with heavy vignetting.

its a bit like going out a buying a ferrari the fitting it with cheap retread tyres , if you've spent the cash for a full frame body then dont sabotage it by scrimping on the lenses.
 
True, very true. Just wanted to see if I could easily get a wide-angle solution on the cheap to decide how much I would actually use it and as a stop gap before spending anymore money. I know you're right though.

Will just have to wait for a while.

Would it not be called "an extension tube" ?

As others have suggested - vignetting will be heavy....

The other thing is even if you modify the mount the back of the lens may well foul on the mirror :eek:

No you wont. When modifying the lens you take bits off so it's less likely to foul the mirror. There are on line instructions that show you how to do this and they're worth a look just out of interest.
 
I believe Ed Bray on here has done it - search it.

Other than that, some non-canon DX lenses will happily mount on FF bodies, as they are in fact EF mount lenses. Tokina's work quite well given the limitations at the wide settings, Sigma's not so well...
