Have I got something wrong with the notion of using multipoint focus modes?
Here's an example.....
There is bird eating on my lawn ....a few inches in front of it is a leaf on the grass, a few inches behind it, is a stick on the grass.
If I frame the bird up with the centre spot on the bird and half depress the shutter, several lights on the 9spot matrix light up. These individually cover the stick, the leaf and the bird. If I take the photo and use the zoom in on focus point function....it's not on the bird! It's not on ANY of these 3 highlighted points, but somewhere inbetweeen. Is the camera using the objects to determine dof and 'choosing' its focal point to approximately cover them all??
More worrying....if I focus on a similar group, sometime the centre light doesn't illuminate with the others. It's as if the camera has decided what IT thinks is the important focal point from the 9 options.
Am I using this metering mode incorrectly? If I switch to single spot focusing the centre spot is the one it zooms into....it works.
But with multispot modes the camera seems to decide what it thinks is important. Photographing birds sat in tree branches is a nightmare!
And don't get me started trying to use it in AFC mode with mult point focusing.....it's all over the place.
I can understand how a bird in flight where the bird was the only object against a clear sky would work. But even then, what happens if the centre spot on the birds head doesn't illuminate and the ones on the edge of the wings ( max contrast) do light up? The head won't be in focus????
Help!
