WooCommerce product image zoom - wordpress

Question

I am currently working on a Wordpress website that supports WooCommerce. I've created a product, and I've uploaded a featured image and other photos for the gallery. But there is a problem i can't figure out. It doesn't matter how big the photo is, if I put the cursor on it, it zooms almost 200%, and that's too much. Does anyone know how to reduce (or remove) the zoom feature? I've been to "sinlge-product/product-image.php" but it seems I can't find any zoom option in the code:
<?php
/**
* Single Product Image
*
* #author WooThemes
* #package WooCommerce/Templates
* #version 2.0.14
*/
if ( ! defined( 'ABSPATH' ) ) {
exit; // Exit if accessed directly
}
global $post, $woocommerce, $product;
?>
<div class="images">
<?php
if ( has_post_thumbnail() ) {
$image_title = esc_attr( get_the_title( get_post_thumbnail_id() ) );
$image_caption = get_post( get_post_thumbnail_id() )->post_excerpt;
$image_link = wp_get_attachment_url( get_post_thumbnail_id() );
$image = get_the_post_thumbnail( $post->ID, apply_filters( 'single_product_large_thumbnail_size', 'shop_single' ), array(
'title' => $image_title,
'alt' => $image_title
) );
$attachment_count = count( $product->get_gallery_attachment_ids() );
if ( $attachment_count > 0 ) {
$gallery = '[product-gallery]';
} else {
$gallery = '';
}
} else {
echo apply_filters( 'woocommerce_single_product_image_html', sprintf( '<img src="%s" alt="%s" />', wc_placeholder_img_src(), __( 'Placeholder', 'woocommerce' ) ), $post->ID );
}
?>
<?php do_action( 'woocommerce_product_thumbnails' ); ?>
</div>
Thank you!

Copy / Paste this code to functions.php on your child theme. Tested and approved ;)
remove_action( 'woocommerce_after_single_product_summary', 'woocommerce_output_related_products', 20 );
add_filter( 'woocommerce_gallery_full_size', 'change_magnifier_lightbox_image_size', 20, 1 );
function change_magnifier_lightbox_image_size( $size ){
$thumbnail_id = get_post_thumbnail_id( get_the_id() );
$attachment = wp_get_attachment_metadata( $thumbnail_id, FALSE );
// Always return a value in a filter hook
return ( $attachment['width'] > 3071 || $attachment['height'] > 3071 ) ? 'preview' : 'large';
}
