I have a 600D that I use a f4.5 L series 100-400 on. If I buy a extender 1.4x ii, can I assume manual focus only? I had read that a firmware update may change that.....

Thanks

It will be MF & don't expect a firmware upgrade that changes that.

Fair enough, I really don't mind the MF, I was just curious. Thanks
