Found this one, you can try it (this is untested):

$objectManager =  \Magento\Framework\App\ObjectManager::getInstance();
$collection = $objectManager->get('Magento\Catalog\Model\ResourceModel\Product\CollectionFactory')->getCollection();
$collection->getSelect()->join( array('custom_table'=> 'table_1'), 'custom_table.id = main_table.entity_id', array('custom_table.sku'));
