Heeft iemand hier ooit van gehoord?
Ik las er een stuk over, dat zeer interessant is.
De camera zo instellen dat hij de foto neemt op het moment dat het onderwerp in je gewenste focuszone komt. De D70 kan dat.
Bij sportfotografie is dat ook lastig, maar de trappingtruuk zorgt er wel voor dat er automatisch afgedrukt wordt op het moment dat het onderwerp scherp is. In de andere gevallen drukt de gebruiker op de knop, en dan is het vaak afwachten of dat moment juist was.
TRICK: You can get the D70 to wait and release the shutter only when an object has moved into a preset focus distance if you set the AE-L/AF-L button to AF ON (set in custom function #15) and then keep the shutter pressed all the way down while NOT pressing the AE-L/AF-L button. This is called Trap Focus. Some people report that this works great for getting sharp macro shots on their D70s. How does this trick work? Presuming you have the camera set to AF-S (CF #02) the camera won't shoot until it thinks the subject is in focus. By setting the AE-L/AF-L button to AF-ON the camera won't focus itself unless you press that button. If you don't press the AF button or focus ring the camera has to wait for the subject to move and when the "in focus" dot lights up the camera will shoot so long as you've been holding the shutter button all the way down. This trick works so long as you have the camera and lens set to AF-S mode and keep holding the shutter all the way down. If you set the camera to manual or touch the focus ring on an AF-s lens while holding down the shutter it will shoot at the wrong time. It's a primitive hack and I doubt it's smart enough to predict subject motion for good results photographing something like horses jumping over a fixed object, but worth a try. It also doesn't work if the subject is moving so fast that the camera doesn't notice it's in focus as the object flies by. Of course you need to prefocus the lens where you want it while not holding the shutter down.
Sorry voor het engels, maar zo trof ik deze tekst aan.
Het werkt in ieder geval perfect.
