On a reasonably bright overcast day like yesterday with light around EV14, then centre focus confirmation light does not display with 2x tc on, light levels reaching the a/f sensor are equal to trying to auto focus an f11 lens. The focus direction arrows work fine at these lower EV though.

Today with the cloud, the light level is EV11 and the centre confirmation light is out with the 400 on its own.

A/F would be very nice but pricey. Guess that would rate a thread, but then again, perhaps not. I must be one of the few here, or possibly the only one, using M/F at the long end.
