Hi, I've noticed exactly the same problem. But even more. When i do an optical preview, at for example F4, the aperture isn't fixed and is spilling from side to side in dependence on position of the lens. This is my second defective DA40. The first one had somehow dirty blades and every picture was overexposed.
