I have a question that concerns the command dial on my X-E1. In manual mode (M), I can press the command dial to access focus peaking. By rotating the dial, I can access two levels of view. I am thinking of buying the 27mm f2.8, which has no aperture ring. Aperture is set by rotating the command dial. Here's the question: When using the 27mm in manual mode (M), does the command dial still control focus peaking and also control the aperture setting? Or does it default to one or the other? If it's the former, how do I adjust aperture? Rico Pfirstinger doesn't address the question in his book. Since the AF on the 27mm is so loud, in certain situations, it would be nice to be able to focus silently in manual mode (M) with the focus peaking feature. Many thanks for your help.
