If in wrong place please move.
Canon T3 has evaluate, centered and partial. Why is what is in front focusing first instead of what I am shooting? Example shot a leaf outside today the grass in front is in perfect focus but leaf is blurred, had it on partial. Thanks

evaluative, partial, and center weighted are all metering modes. They're used for judging the amount of light in a scene and help gauge correct exposure. They're not involved with focusing. To get focus quickly, you need to have your area of focus at the active AF point. With more lighting, AF is also faster (since the scene has more contrast).

Did you have the camera set to use all the focus points?

It doesn't know that the leaf is your subject, so will tend to focus on what is nearest the camera, in this case the grass. You are much better off selecting a single focus point and placing it over your subject to focus. That way, you tell the camera exactly what to focus on, rather than letting it decide for itself.
