The exact spot where light is being focused onto the sensor doesn’t always end up in the same place. Automatic selection AFWe spend a lot of money on camera gear – and expect it to work as described – but what we’re not told is that from manufacturer to manufacturer and lens copy to lens copy there are almost always slight variances. It is effective for capturing birds moving erratically that the camera would have trouble tracking with Zone AF.
This mode uses a large group of AF points selected by the user to focus and divides the AF area into three zones - left, center, and right. Zone AF is effective for capturing fast-moving birds while you pay attention to the overall composition. This mode uses a group of AF points selected by the user to focus and divides the AF area into nine zones. It is effective for capturing erratically moving subjects. With this mode, a cluster of nine AF points - a box of eight secondary AF points surrounding the primary AF point selected by the user - is used to focus. It is effective for capturing subjects that make small, erratic movements. With this mode, a cluster of five AF points - four secondary AF points surrounding the primary AF point selected by the user - is used to focus. Single-point AF is effective when the subject is obscured by such objects as a cage, a fence or branches. This mode uses a single AF point that is selected by the user and slightly wider than Single-point Spot AF. Spot AF is effective when the subject is obscured by such objects a cage, a fence or branches. This mode has the narrowest AF sampling area selected by the user. Different camera models have different numbers of AF points.ĪF area selection mode Single-point Spot AF It is effective for birds moving very vigorously or whose movements are unpredictable. This mode focuses using all AF points (the entire AF array).
