#11. "RE: Shutter release vs focus mode question on D40" In response to In response to 10
The only thing they mentioned was that the light was not too bright when they tried it. I don't know if that affected the camera's focusing ability or not.
I set up the camera using these settings: In the Custom Setting Menu (pencil) go to: 02 Focus Mode Set to AF-C
12 AE-L/AF-L Set to AF ON
I think you may need to click on "OK" or something like that so that your settings are remembered.
Now as long as you hold down the AE-/AF-L button the camera will track a moving object (within reason) and continuously focus, and you can press the shutter release button to take the picture whenever you choose. Or if an object is stationary you can press the AE-L/AF-L button once to focus.
That's all I did and the camera worked perfectly a couple of days ago when I had it.
Hope this helps. If I can come up with anything else to help I'll be happy to do so. I have been shooting in this manner with my D300S every since it was new and would never go back to the old method of focusing with the shutter release button.
