Do you have your camera set up to use manual-focus lenses? That is, in Custom Menu 3 have you set "16. Using Aperture Ring" to "2 Enable"? Then in Rec. Mode Menu 3 have you set "Button Customization" > "Green Button" > "Action in M/TAv Mode" > "Tv Shift"?
Have you set the button to the right of the OK button (with the self-timer icon) to "Exposure Bracketing"?
What mode are you shooting in? With A lenses, are you using the A setting on the aperture ring, or are you trying to set the aperture manually? Are you using manual or auto ISO?
I use auto bracketing with manual lenses all the time, so it definitely can be done.

Thank you Noel, it was the button to the right hand side of OK that was not set. Now working perfectly.
Merci ...
