slight arc and the focus plane will thus be located slightly behind your subject. This

could be more noticeable when working close to the subject and/ or when using wide

discussed later in the text in relation to exposure and metering. It may sound difficult to

select the focus point each time, but it is actually very feasible and will likely become

instinctive. You may even find that you start to set your focus point with your thumb on

the Multi-Controller as you approach a scene before even bringing your camera to your

eye. For example, if you know the subject will be on the right side of the frame, you can

click, click, click the Multi-Controller to the right a few times so that the active AF Point is

already on the right as you bring the camera to your eye.
