Customer Reviews on Sigma 1.4X EX DG APO Tele-Converter AF for Canon EOS Cameras£224.99

I had to return this as it would not fit my Canon EF 75-300mm. It did fit my 28-135 but the autofocus di not work even in bright sunlight, it just kept hunting for the focus but couldn't find it. Seems odd to have these problems when this was supposed to be for Canons. Have now got the Kenko version which works fine but have not yet checked the quality of the pictures it produces.
