You can retrieve the WordPress default image sizes (as well as set custom image sizes) using Advanced Custom Fields using the following:
<?php $image = get_field('image');
echo $image['url']; //This is the full image
echo $image['sizes']['large']; This is the large image
echo $image['sizes']['medium']; // This is the medium image
echo $image['sizes']['thumbnail']; //This is the thumbnail image
?>
Tie this information together with Lightbox Plus like so:
<a href='<?php echo $image['url']; ?>' rel="lightbox">
<img src="<?php echo $image['sizes']['large']; ?>" alt="<?php echo $image['caption']; ?>" />
</a>
Advanced Custom Field size information.
