No focusing issue, my only complaint is that with the adapter, it is lengthly, but for that kind of shooting, i use a monopod to help stabilize it. I also use back button single spot focusing. Since my 7 came with the kit 18-150, which is much lighter than the 18-400, the 18-150 may become my walk-around lens, saving the 400 for long range sports and nature.
