Google Maps v3 fitBounds() Zoom too close for single marker

Question

Is there a way to set a max zoom level for fitBounds()? My problem is that when the map is only fed one location, it zooms in as far as it can go, which really takes the map out of context and renders it useless. Perhaps I am taking the wrong approach?

Thanks in advance!

I like mrt's solution (especially when you don't know how many points you will be mapping or adjusting for), except it throws the marker off so that it isn't in the center of the map anymore. I simply extended it by an additional point subtracting .01 from the lat and lng as well, so it keeps the marker in the center. Works great, thanks mrt!

// Pan & Zoom map to show all markers
function fitToMarkers(markers) {

    var bounds = new google.maps.LatLngBounds();

    // Create bounds from markers
    for( var index in markers ) {
        var latlng = markers[index].getPosition();
        bounds.extend(latlng);
    }

    // Don't zoom in too far on only one marker
    if (bounds.getNorthEast().equals(bounds.getSouthWest())) {
       var extendPoint1 = new google.maps.LatLng(bounds.getNorthEast().lat() + 0.01, bounds.getNorthEast().lng() + 0.01);
       var extendPoint2 = new google.maps.LatLng(bounds.getNorthEast().lat() - 0.01, bounds.getNorthEast().lng() - 0.01);
       bounds.extend(extendPoint1);
       bounds.extend(extendPoint2);
    }

    map.fitBounds(bounds);

    // Adjusting zoom here doesn't work :/
