AF AND PRE-FOCUS
Coal tits are very agile little birds and rarely stop moving, so they certainly won’t hang around while you compose a shot. Prefocusing enables you to frame the scene in advance so that you can release the shutter as soon as the bird lands. to achieve this, use the AF point selection to manually select a single AF point, positioned over the wooden peg.
For this technique to work successfully the key elements must occupy the same focal plane.
