Excerpt: Spark is the latest creative optical lens from Lensbaby. Like other Lensbabies, it has a flexible bendy tube that you push and pull (they say squeeze) to distort the focus points in your photo and create whacky results. It appears to be aimed at the youthful and adventurous photographer, so epz oldie, Peter Bargh, takes a look to see if he can be rejuvenated by the lens.
Pros: Easy to adjust, No locking so quick and resposive, Threaded to accept accessories, Circular bokeh
Cons: Harder to get good photos than a normal lens, Plastic filter thread could easily be cross theaded
