Limit entries of WPQuery

Hello everybody,

when using this query, i don’t get unlimited entries, they get cut of at 10 entries.

$metaQuery = array(
	'relation' => 'AND'
);

$metaQuery[] = array(
	'key' => 'isvisible',
	'value' => '1',
	'compare' => '='
);

$args = array(
	'numberposts' => -1,
	'post_type' => 'portfolio',
	'meta_query' => $metaQuery
);

$entries = array();
$the_query = new WP_Query($args);
while($the_query->have_posts()){
	$the_query->the_post();
	$entries[] = array(
		"id" => get_the_id(),
		"title" => get_the_title(),
		"mapentry" => get_field("mapentry"),
		"street" => get_field("street"),
		"postal" => get_field("postal"),
		"city" => get_field("city"),
		"link" => get_permalink(),
		"thumbnail" => get_field("thumbnail")
	);
}

When i print_r this query, i get a:
DESC LIMIT 0, 10;
at the end…?

So, where is the knot? ??
