Photography Question

Manual Focus -vs- Auto Focus


Say you're at the zoo, you find a creature to shoot (pictures) but it's behind a wire cage. When using auto focus, the lense tends to pick up on the bars of the wires rather than the subject. When selecting manual focus, the subject instantly becomes very focused and the bars seem to fade away.

How is it that this happens? Why doesn't the autofocus allow for the wire bars to disappear?

Thanks...

  Because the logic programmed into the camera is not as intelligent as you are. It cannot discern what your intended subject is, so will generally focus on the nearest, contrastiest subject that the sensor covers.

  Cheri - are you talking about the S5000? I also have the same camera - and have managed to take some pretty decent shots with fences. My favorite thing to do of course if I can is get up close to the fence and line up the lens with a hole in the fence - then no problems at all! But if you can't do that - you have to practice with different settings to get it to "ignore" the fence.
