Thought the sameI didn't realize that BIF was the only thing a 400mm lens is good for...Show us some BIF images with your Canon 400 F5.6.I'm quite satisfied with how my Canon lenses work on a MB IV T + A7RII. But then I also rarely take pictures of bells & whistles...Thanks, but it was definitely (or it was supposed to be...) a BT-IV. And I would not be happy with a new camera that would not allow me to use the bells and whistles with my lenses. I think I will learn to be happy with my situation, and just wait for the perfect camera to come along. Hopefully that will happen at Photokina...![]()

Anyway, it would be perfectly capable of doing that as well, unless one expects technology to do all the thinking & work.
