Just like most babies (except perhaps Gilly’s baby), the Lensbabies are growing up in size and in cost. Their Velvet 56, available for various DSLR and mirrorless systems is now going for $450 at Adorama and by various at Amazon.
CORRECTION: blog-post title initially showed price as $50. It is/was $450. Probably cause of typo: the dollar-sign being shift-4.
