CANON 100f2.8 is usm (1 Viewer)

Hi please correct me if I am wrong I believe this lens cannot adopt a 1.4 converter?
I am hoping someone knows better? And if it does will it retain A/F. Not from the canon camera point of view. IE is the converter fully electronic?
Kind regards Mike.
 
The non IS version certainly won't take a canon converter as its not physically compatible. I'm sure I read that some 3rd party converters will. Somebody should be along shortly to clarify which ones fit (Kenko?).

I have this lens and Canon tc and can confirm will not fit. I do seem to remember that Kenko does and there is a strong school of thought that there is little image difference.

Thankyou for your replies, thus the sigma 1.4 doesn't fit
The kenko 1.4 pro 300 DGX does fit. And maintains a/f Tried these in shop on my canon 100 2.8L is usm today
Thanks again mike

Apologies the sigma does fit but there was a nasty sound coming from the focusing action on the canon 100 f2.8 is ism lens. I obviously stopped very abruptly at that stage of the test. So be careful people!
Kind regards mike
