I used the Canon x1.4 Extender II on the 40D with the pins at the rear of the Extender taped up, so they could not make an electrical connection with the 40D and return an “Err” message. 
This set up gave me an effective focal length of 1285mm at F12.6 and the solar disc nicely filled the field of view.
A full aperture Baader solar filter (OD=3.8) was used.
