Very rarely I use #2 on the 5, although it's quite reliable. FWIW, I did some testing with the automatical AF sensor selection of my 1N earlier today and found it to behave "as expected". The sensor with the nearest subject was always selected, as long as it could successfully achieve focus. I didn't notice any preference for the central sensor. I tried with several lenses. With the 35/2 there were frequently more than one sensor selected, while with the 200/2.8 it selected mostly one sensor and also the "failure rate" was much higher. Probably a matter of DOF. Focusing the 200 through some branches would sometimes result in a blinking AF confirmation light, even though the focus was already seemingly achieved on a bunch of branches. Sometimes it would first try to focus on the nearby branches and then decide to focus on the grass in the background using one of the peripheral sensors. Probably again because it could not achieve focus on the branches reliably. <wild guess mode>If there are several strong patterns at slightly different distances under the same sensor, AF might fail because the camera can't decide on which to focus. </wild guess mode> Anyway, in all cases where the sensor on the closest subject could reliably achieve focus on it with manually selected AF sensor, this sensor was also selected automatically and focus was achieved. Even when the camera was almost prefocused on one of the other subjects.
