Originally posted by Ole Re 1): Use the AF button on the back to lock focus. Press and hold it to keep focus locked. Then recompose and half-press the shutter to meassure the exposure and trip it to take the shot.
Re 2): Lightly touch the shutter button to turn the meter on. Press the AE-L button to lock exposure. An asterisk (star) is shown in the view finder. Recompose and shoot. Custom function 4 sets how long the meter stays on. You may want to set it to its maximum value.
Re 3): Follow #2 then #1. Or set custom function 5 to 2 (on). This will lock the exposure when you lock focus using the method in #1.
