Canon Lens Mount Converter Ef-S Lens to 5D Mark III

Camera: Canon 5D Mark III
Lens: EF-S 10-18mm IS Macro

Is there a Canon mount converter that will safely turn my EF-S lens to an EF lens in order to fit my 5DM3?

Thanks for asking about an EF-S to EF lens converter for Canon. No, you cannot make a smaller EF-S 10-18mm lens fit onto a larger full frame 5D Mark III. The image circle on the 10-18mm lens is too small to project light to cover the entire full frame sensor of the 5D M3.

EF versus EF-S Lenses

It's very easy to get confused on lens /camera compatibility when it come to EF and EF-S lenses and if they'll work on APS-C crop or full frame sensor cameras. I shot a short video on this exact topic and many viewers have commented on how simple and helpful it was for them to watch:

I hope this helps!
Thanks,

I was very sad that I had to trade in my Sigma 10-18 lens when I bought a 5D.
However I bought the Canon instead and that’s amazing!!
