title: Creation of a 50,000λ long needle-like field with 0.36λ width: comment.
abstract: In a recent paper, a method for the generation of a long, narrow needle of light was proposed [J. Opt. Soc. Am. A 31, 500 (2014)]. The implications of this on our appreciation of the properties of Bessel beams are discussed.
