I want to buy a Canon EF 400mm F/5.6 L USM for my Canon 7D. I already own a 1.4 mark II extender. I know the extender will work in combination with the Canon EF 400mm F/5.6 L USM but the autofocus will not work because the diafragma is to small. Does Magic Lantern have a solution or does anybody know how to get the autofocus working?
Thanks in advance,

Wiek :)
